    Yes, responsiveness and ease of use, are really the only reason to go with VR. (Oh, and Ad-Detective is preat slick too!) But I couldn't stand using Nero Vision for cutting commercials. If you use NV, you'll probably have to use DSD in order to have much success at it.

    You don't need additional equipment. At the bottom of your Tivo's Now Playing List you should see your PC listed as a folder. (If you have TivoDesktop installed on you PC). Just open it up and start uploading files back to your Tivo. They don't have to be just .tivo files either.

    Finally, you don't have to buy VR to reattach the .tivo headers to your freed/edited .mpg files either. My little app Tivo Attach does it just fine, but VR is 10x more convienent.

    Greg:

    One thing I have found with MPEGInspector is that all .tivo files have an audio offset, and each .tivo has a different offset. Running MI on a post DSD .mpg shows this. I have found that VR corrects this when it puts out your edited file to mpeg. If you put the file through something like ffmpeg, the audio offset is lost, but not corrected.

    Have you also discovered these audio offsets? I think it has implications for complaints about audio sync in the final results.

    I can't believe it, but when I go to create chapters in Nerovision4 the buttons are gone. The "automatically detect chapters" button is there, but sometimes it works, and sometimes it doesn't (even though the CPu is working 100%) and I have no manual buttons for adding, or deleting, chapters.

    I wondered if someone - wink wink - could check to see if they're having the same issue in NV4?

    Nero won't be getting any more money from me for future products until they've been tested and proven.

    I am no MPEG2 expert (in fact I don't know anything about their file structures), but is this offset you are talking about at byte 12? I noticed a lot of tivo files have different values here. 0x3400, 0x3800, 0x4000, 0x4400 etc...

    I was asking Dan at VR why his reattached headers don't respect that value, but I am not sure he understood my Q. (Probably didn't help that I didn't understand what I was asking.)

    I don't know about the location in the file of the audio offset stat. MI reports in its main summary screen that the audio starts XXX ms before/after the video.

    xxx has been anything from a few ms to well over 200 ms. The average is probably over 100 ms.

    If I take the mpeg into VideoRedo, and do nothing but output it back to mpeg, no audio offset is reported in MI on the new mpeg. I believe the audio is at that point BETTER synched to the video, from my observation.

    I have not tried to take the original .tivo into VR and output it to mpeg to see if VR also "corrects" the synch. I'd have to compare a post DSD-.tivo to a post VR-.tivo with MI.

    In contrast, FFMPEG will drop the audio offset, without actually correcting the synch.

    My theory is that TiVo puts a random offset between audio and video streams into each recording. I don't know why it would though. However, if I really look, I can tell there is a discrepancy between audio and video even with a TiVo recording simply played on the TiVo.

    Ok,

    I'm the original poster of this message. I've ordered Nero, and it should be here soon. This is what I want to do. I tape a few shows like Lost, Alias, Battlestar Galactica. I want to create DVD's with 3 episodes each on them. Editing out commercials seems pretty time consuming, so I'd like to do the entire file (is that possible?). I'm still unsure if I should use best or medium quality.

    Also a couple more questions. I have a small 19 inch lcd tv with a digital cable box. Will I get a better picture quality if I move the tivo to a normal crt tv?

    Also, is there a significant reduction in quality from Best to Medium? Or Best to High?

    Thanks

    Nero Vision will squeeze pretty much whatever quality tivo file (after freeing w/ DSD) you throw at it onto a DVD. This squeezing/compression looks really bad, IMO.

    I've never been able to fit more than two 1-hour episodes (recorded High quality, w/ commercials removed) on a DVD w/o compression.

    In order to fit 3 episodes on a DVD w/o compression you are going to have to record them in Medium quality. A side benefit is that the will by in a proper DVD format (352x480) so the transcode portion will be quicker.

    Cutting commercials using Nero Vision is slow and painful (again IMO). VideoRedo is very quick. I can do a hour show in under a minute. (If you let AdDetective run first it will take longer, but makes it much easier.) Downside; VR is not cheap.

    I'm finally sending a complaint to nero and I hope everyone esle who's unhappy with nero7 issues will do the same.

    Tittle subject: "Problems found in N7 ver. 7.0.8.2, and NV4 ver. 4.1.0.13"

    Body of text: "I've become a more than a little dismayed by all the bugginess found in Nero7. Loyal paying customers shouldn't be treated as beta testers. In other words I think it was bad business practice to release Nero7, when it should be obvious to everyone - unfortunate enough to have purchase this product - that it hadn't been thoroughly tested first.
    1. The update function still doesn't work. That is unless un-installing Nero7 is the goal. I know at least 2 other Nero users besides myself who have had to do clean - re installs of Nero7, after attempting to use the update features found in the "new product setup" menu. Could you at least inform people that the update feature should be avoided until the bugs are worked out of it?
    2. Although the newest release of Nero7 fixes the issue that made it impossible to create a functioning animated menus, By the way I wasted many DVD-R Discs trying to figure out what the problem was and although you must have my e-mail address I was never contacted by Nero informing me that there was a known problems with my product.
    3. The main reason I'm taking time to write you today is that I'm now having problems when trying to "create chapters" in nerovision4.
    a. Chapter creation only functions properly when performed before the movie file has been edited in any way.
    b. If chapter detection is attempted after editing the movie, the chapter detection runs and runs, with 0% progress."

    TJ:

    If you edit the files, can you output to mpeg? If you can then you could import the completed mpeg and then define chapters - no editing. That might get you going, even if it is nothing like it should be.

    I think i'll try to see if i can get a successful result using VideoReDo to cut the ends off - movie - then add effects and chapters and menus in nero, and see if I can get a successful burn that way. As it turned out even if i created the chapters first, then edited... the burn process locks up with 5% progress and NV4 need to be ended in task manager. :mad:

    Another note to Nero tech support was in order: "After creating a DVD movie that includes editing and chapters, the
    burn process hangs at (5%) transcoding menus. At that point the burn
    process freezes, and the program ended by windows task manager.

    Alternatively if the movie isn't edited, but chapters are inserted,
    the burn process is successful.

    I think I'll go back to using nero6 until you get these problems worked out."

    One serious answer: with Nero and EMC, you keep hoping the next update will take out the bugs, give you back what you had three updates ago but with some new features.

    I beat (and still do sometimes) my head against the wall with both programs. until I finally realized the awful truth: they're not very good.

    So for Tivo files, I edit with Video ReDo, transcode as necessary with TMPG's Enc 3, and burn with either TMPG's dvd program or - new favorite - DVD Lab.

    As far as I'm concerned, the worst of Nero and MCE isn't even the fact that they don't work easily - or at all, in the case of EMC 8. The worst is how they gum up/slow down/take over your system.

    All the other tools I've mentioned here work well - I forgot to mention Direct Show Dump, which I'll use in combination with TMPG's mpeg editor if I don't want to use Video Redo, and the promising open source editor mpeg2cut2 - and none of them wrap vines around the rest of my computer.

    Your correct: The latest update was supposed to fix the animated menu's bug - after burning the dvd player would play the animation only - and I got my hopes up too high, only to find that the project won't burn at all if it contains animated menus. Took me a couple hours to track down exactly what the problem is.

    Nero is very unresponsive even on a fast system, but it doesn't hog my system too much, especially if i set the burn priority to "below normal". I'm burning a project right now, minus any animated menus of course. :mad:

    What I like about Nero - besides the fact that DVD Shrink uses Nero's burning rom :D - are all the bells, and whistles; animated menus, chapter detection, and a nice looking, user friendly interface. And Nero is what I'm used to and humans tend to avoid change, but I'm going to have to check-out DVD Lab and other options, because next time I'm NOT going to automatically go with Nero again.

    VideoReDo is a great little product, and I'm sure it will only get better with time. You can tell just by looking at their web site that the VideoReDo care about their customers needs. Or at least they understand that customer loyalty depends on good customer service.

    I just burned an animated disc using the "golf" template (to an .nrg image) no problem. (latest build: 7.0.8.2)

    Gotta ask... are you still using your method of adding encrypted .tivo files rather than using VR or DSD? Maybe therein lies the problem.

    Yep ver. 7.0.8.2, with NV4 ver. 4.1.0.15

    I did try using a file edited in VR, used a jpeg image for the backround, and animated buttons in menu. I guess it could be that the file I'm trying to use is corrupt - not sure why i think that - ruling out everything else... i'll have to try it again tonight using a a different file.

    thanks for checking your version for the same problem :up:

    Always try another file before thinking it is something else.

    My policy - I have MyDVD - is to do everything in other programs, and then import the final content into MyDVD for burning. Just import the files and burn DVD with no other work on them. MyDVD manages to accomplish this in general.

    The thing about MyDVD is that it doesn't do 352x480 output. Everything therefore gets transcoded either to 720x480 or 352x240. That's a big negative over what you can apparently do with Nero - skip transcoding.

    With that in mind, did you see what I posted last night?

    Interesting stuff (to me). This is pretty much what you and I discovered previously, but I had forgotten already. :rolleyes:

    I've been reading the forum about burning TiVo DVDs and well, I am quite confused. No, actually, I am totally confused. Matter of fact, look up "confused" in the dictionary and there you'll find me.
    I read a CNET review of TiVo togo and they addressed burning DVDs and they made it sound like a piece of cake. However, in reading some of the comments here, I am wondering if they sugarcoated the process. All I want to do is transfer a program I've recorded via TiVo to a DVD disc that will be playable on DVD players attached to a TV set (editing out the commercials would be nice but not totally necessary if it's going to cause me to have a stroke). I was under the impression all I needed was an external DVD burner for one of my PCs and the Sonic MyDVD software. However in reading some prior posts, it seems there is a lot more to it than just that.
    Can someone either explain what exactly I need to purchase or point me to a link that outlines exactly what I need to do, please? I'm not computer illiterate by any means but when it comes to making DVDs, well, let's just say that other than being able to spell D-V-D, I am a total idiot.

    Thanksk in advance for any assistance...

    1. Don't believe everything you read.
    2. Welcome to the club.

    3. MyDVD is probably the worst choice. People are doing much better with Nero. If I didn't already have MyDVD (or if I made many DVDs) I'd get Nero or something else.

    Others are better with details...I am sure you'll get more advice.

    Its good you pointed it out because I had not been reading that thread since early in its life.

    You are getting the results we discussed...lucky you with Nero.

    You are most likely managing to get Nero to not only accept the 352x480 output resolution, but also the same bit rate from the .tivo (2.5mbps) Changing bit rates is time consuming too. I never tried to measure if there are important differences between bit rates (file size), or if transcoding BOTH bit rate and resolution takes longer than just one alone. File size will affect time just because of longer time for disk I/O, but processor time ????

    The SAs that use MP2 audio have to have their audio transcoded to AC3 by Nero (or whatever program.) Audio transcode is a fraction of the effort of video.

    Your 4 hours of Medium on one DVD gives me pause because that should be too much for the DVD; did you edit out commercials? That could get you under the wire.
