Discussion in 'TiVo Series3 HDTV DVRs' started by bkdtv, Oct 26, 2007.
I held down the shift key for too long. My second post was in bytes.
One piece of information I can add: I was able to transfer and play back a PAL MPEG2 file (544x576i) on the Series 3. In "native" mode the video is converted to 720p for playback.
The results are not ideal--better would be if "native" actually yielded 576i for deinterlacing and processing by my Lumagen video processor--but not bad at all, considering. A little juddery, a little ring-y, but the TiVo has the friendliest UI by far of any media player I've ever used, and that counts for a lot.
This is great. I'll have to experiment with more formats.
Does the same thing happen with 640?
TivoPony was referring to supported functionality. That is all Tivo officially supports. There is plenty of stuff you can do that TiVo does not officially support.
There are a number of different posts about the ability to transfer MPGs. In this post, a member mentioned that they were able to transfer a play a high-definition MPG, but it played with odd skips and jumps.
To test with high-definition recording that did not originate from the TiVo, I downloaded this 22.5Mbps transport file (190Mb) from the HD-DVD test pattern site -- it is a short, repeating loop of a man running through the park. I converted this TS file to MPG using the free HDTVtoMPEG2 utility. It transferred and played fine on my TivoHD.
I did not see any comments on transfer speed when copying videos from PC to TiVo. When we have more information on that, I'll add it to the FAQ.
I've experimented with this a little and have had mixed success with playback of mpeg2 files not originating from a Tivo. A few examples:
1. I have several HD mpeg2 transport streams from a PC QAM tuner. Tivo Desktop can't see .ts files so I convert to .mpg and then TD can see them and I can feed them to my S3s. Some of them play back without issue, some will refuse to play back beyond a certain point, some will play back but no trick functions will work.
2. I have had very good success playing many DVD compliant mpeg2 program streams. Glitch free playback and all trick functions work fine.
3. I even tried playing back mpeg2 files from ReplayTV - those play back fine but no trick functions work.
4. Any HD mpeg2 file originating from my S3s seems to play back fine even after I convert from .TiVo to .mpg and edit out commercials.
So I think that's why TivoPony warned us that Tivo currently only supports HD playback of files originating from S3. It seems like you can get non S3 mpeg2 files to work in some cases, but the S3 decoder seems to be pretty picky to get full functionality working.
If you try processing your flaky mpg sources through VideoRedo (even without edits - it still remuxes on save) do you get mpg's that are fully playable?
Sorry, if this is covered and it may be more a Windows' issue but....
Is there a way to "redirect" the My Tivo Recordings to another location. My C: drive is getting a bit tight and I have usb drives hanging around with space. I know I can manually move stuff out of that directory, sorry folder but if I could just get TivoToGo to just use those usb drive(s) initially I would save a step and also schedule a bunch of stuff overnight and just let it run.
I looked over TivoDesktop and did not see any option to change folder locations.
Thanks in advance
Look at the File Locations tab in Tivo Desktop, which you can open by selecting File -> Preferences.
You'll need to move your previous downloads to the new folder, as indicated by the tip at the bottom of that tab.
I don't have VideoRedo. I use Womble Mpeg Video Wizard for mpeg2 editing (it has been around much longer than VideoRedo but is similar in capabilities - frame accurate editing, only transcodes at cut points, etc). I wouldn't categorize the mpg sources that don't work properly with Tivo decoder as "flaky". They play back perfectly OK with Videolan VLC, Media Player Classic and some other players on the PC. The ReplayTV mpg files (recordings at medium quality) play back in all DVD players I have tried (and the software I use to make DVD VOBs doesn't transcode the RTV video as it is DVD compliant, just the audio to AC3). So if anything I would categorize the S3 mpeg2 decoder as "flaky".
Don't get me wrong - I'm not saying that TTCB capability is critically flawed. I'm just trying to explore exactly what works and what doesn't work. I'm very happy that at least mpeg2 files originating from S3s (SD & HD) can be edited of commercials and then thrown back at the S3s and play back perfectly. Also very happy that commercial DVD originating mpegs seem to play back fine as well. Note that these notes are based on a relatively small sample of files I have tried so far, so may not representative of a much larger sample size...
Does anyone know if the directory you select for TTCB from a Mac can be set to a USB hard drive? It seems like it only works if the directory is on the drive Mac OS X resides on. Is that true? I already tried putting an alias (shortcut) to the external drive in the default directory, but that didn't seem to work either. It would be really lame if I couldn't get that to work because I don't have much space on my OS hard drive and tons of space on the external one.
Don't have a Mac, but on my Win XP machine I put shortcuts in the Tivo folder to files on my external USB drive and they transfer fine (Using Tivo Desktop) - so that indicates it should be possible on a Mac.
Is there any word on when Toast will be updated to support the Series3 and THD?
My sample size equals exactly one (so far) and I really appreciate your efforts--I suspect though that a separate thread would be best for this.
My experience (VideoReDo) was merely to edit-and-output an HD TV show to .mpg--the result plays perfectly on the PC but not on the S3. There is an odd "racing" effect that occurs several times a minute; the video jumps and the audio races to keep up. Interestingly it is in SYNC to the end, but it's unwatchable for the jumps.
I've used VRD with HD for a couple years but .tivo files are completely new to me. It will be interesting to see what DanR (VRD developer) finds when he gets his new TivoHD in a week or two. But given the past, he No Doubt will figure out the problem(s) and unless the solution lay exclusively w/in the Tivo he will fix it.
VideoRedo has a free trial. Give it a shot.
Has anyone with VideoRedo tried the TiVo-VideoReDo-AutoProcessor ("TVAP") program?
Every time you transfer a recording from the Tivo to your PC, this free utility automatically runs it through VideoRedo to remove the commercials. The recording can then be transferred back to the Tivo without commercials. More information and a download link here:
I haven't tested it with the Series3 or TivoHD, but intend to do so this weekend.
So with this and TD Plus you could automatically TTG new recordings to the PC and have them run through VR to come out with a comercial free .tivo or .mpg?
I've tried various such utilities in the past but I am pretty picky about cut points and I've never seen one get it 100% right. With my editor (Womble) as I'm sure is the case with VideoRedo after some experience it only takes about 5 minutes of editing per 1 hour of show to remove commercials and then maybe another 10 minutes or so to save to disk (for HD content, less for SD content).
In my experience, VideoRedo is fairly accurate for series programming from the networks. Sometimes it will miss a commercial, but I've never seen it cut part of the actual series program. It is much less accurate when it comes to sports and other live broadcasts.
Sorry, I'm a jackass. I didn't realize I had toggled to "panel" mode. all good now.
Is there anyway to use TTCB with content origoanlly from HD-DVD or Blu Ray?
Anyone else have a hell of a time editing tivotrans.dll?
I originally opened it, saved it as a differnt file name, killed all the running Tivo processes, deleted the original, and renamed the edited one. When I checked my work, the edited file, now named tivotrans.dll still had the default settings.
I tried many different variations to get the correct setting into tivotrans.dll. Eventually I had to go into safemode and do the editing there to get it to stick.
That said, I now have 720, 6000, 6000. I transferred 2 files. One came out great, the other squished.
The first file is 640x368, the second is 592x256.
How is TD supposed to handle different resolutions when the file transferrs?
