    What viewer are you using? Try VLC, I'm rarely disappointed by it. Also you can use MediaInfo to get information about your source file.

    Just FYI, I recently did a bunch of trial re-encodes (using HandBrake) on an OTA football game. Here are my very subjective conclusions, all as viewed by VLC on my computer:

    1920x1080i original, very good quality HD
    1280x720 target ATV2, still very good quality
    1024x576 target iPad, still pretty good quality
    960x528 target iPhone4, slight imperfections
    720x400 target universal, not very good for HD
    480x274 target iPhone, certainly not for HD

    It doesn't matter if I use QT Player or VLC, the files look pretty much the same.


    I am not sure that is relevant:
    First of all info the original TiVo file format is what it is - and it looks good on the TV, but bad on my Mac after simply downloading from the TiVo and decrypting.

    Second of all, I am looking the decrypted version of that file, which shouldn't be changing the quality.

    Third, merrily looking at numbers (file specs) doesn't really say anything about what the video will look like quality-wise: You can have a 1920 X 1080p, 7.1 channel 256 KHz audio file that looks like absolute garbage - all the numbers are going to really tell you is how large the file will be that plays back that garbage.
    Or another way to put it: all 100 W stereo systems sound the same, and 200 W stereo system sounds even better.

    For what it is worth, the original 3 GB TiVo file was reported as:
    6,239 Kbps, 720X480, 29.970 fps MPEG NTSC video
    384 Kbps, 48KHz 2-channel MPEG Audio


    I am simply trying to determine if:
    a) All video downloaded from TiVo will look bad (perhaps TiVo is putting some sort of limit on the quality that can be downloaded from the box) - and has these interlace type line artifacts in it.

    b) It is because I am still using SD content as source (but that doesn't exactly explain why it looks "good" on my TV).

    c) I am doing something wrong (having never down this before)


    I screen-snapped an image from the video that shows what I am seeing. The video was played at its normal size - I did not make the playback window larger. In the video note the actor on the right's nose, eyes, hair line, jacket edges, and hand. Also look at the wall sconces on the right.

    Your computer is displaying the file as is. Your tv is line doubling and smoothing the output to make it APPEAR better.

    You need to switch to HD program streams and use those on your computer. The Tivo is not down converting or limiting the output of the file in any way.

    If the original program material is analog, the tivo is encoding it to mpeg2 but thats true for what you see in the tv as well.

    The sooner you drop the SD analog material the happier you will be.

    Gotcha. That makes sense.

    I never upgraded my cable service to HD, because when I viewed it at other people's homes, it just didn't look any better, in fact in some ways it looked worse.

    Figured the cable co was significantly compressing the data...

    It never made sense to me to pay the cable co significantly more each month, have to live with their cable box, and have an insignificantly better, or worse, picture.

    Considering the Elite, so that will push me there...



    Thanks for the info, it was exactly what I was looking for.

    The lines are because you don't have deinterlace filter turned on in your player. VLC and various other players have many deinterlace filters that will get rid of those lines when viewed on computer but they are not enabled by default. For VLC visit:
    Tools->Preferences->Video->Deinterlacing. I have mine set to "Automatic" and Mode=Blend.
    Nevertheless, as mentioned SD will still look like crap on most computer monitors even without those lines.

    Wow thanks for that tip - it really cleaned up that noise.

    Although it doesn't look like you can set it as a preference on the Mac build. There is a menu to enable Interlacing and set the Mode, but you have to manually set it for each viewing.

    Noted - I also assume the above tip doesn't help when viewing a file encoded for and then watched on an iDevice, because those apps don't adjust for the deinterlacing....

    Still pondering purchasing an Elite, which would force my hand at the move to digital, but I hear that the Elite still has slow navigation menus, so wondering if I should wait for Series 5...

    I think your display issues are mostly related to your recording quality/ and software. I process many files from the TiVo and replaytv and other capture devices and lots of settings van make a huge difference in how they appear. I have many sd encodes that look pretty good, even blown up on the 60 in or bigger screen.

    For HD sources, after TiVo decoding the files look great through my set top box (brite view) or even streamed from server direct to my panasonic tv. Unfortunately, I think macs are expecting only certain file types and don't like dealing with other types. Even non hd from my 1999 replaytv recorded off a good signal still looks good after decrypting( different encryption than TiVo) and removing commercials and such. same with TiVo sd, just hd looks even better.
    Maybe mess with other settings and accelerations in vlc on the Mac to make it look better? Also check your signal into the TiVo to make sure it is as clean as you can get, that can make a big difference too. I stream converted shrunk videos in sd from my server to my iPad or to other tvs and even they look pretty good, so I would really try changing some settings around. You could always get a good set top box to archive your shows and watch later, or even watch them back later on using streambaby, which works good too.

    It was just a matter of setting the interlacing setting properly for playback on VNC like the previous poster suggested.

    Now I just have to find a way to build that process into the re-encoding process so that it will play back cleaned up on the iDevices.

    I haven't looked, but I assume that handbrake can do that.

    Hello,

    I used to use kmttg with my Tivo HD without problems. I recently upgraded to a Tivo Premiere, and I keep getting the following message:

    Failed to retrieve Now Playing List from DVR-0F91
    Exit code: 35
    Check YOUR MAK & IP settings

    curl: (35) Unknown SSL protocol error in connection to 10.10.10.122:443

    As far as I can tell, MAK and IP settings are correct. IP was autodetected. If I switch to Java method, I also get a failure. Seems to be some communication issue, but it can retrieve the iPad remote stuff just fine. Anyone have any ideas? I tried disabling the firewall, but that didn't help.

    Do you have the options set properly for the new TiVo on your account at tivo.com?

    Since you have the newer Tivo, have you gone to tivo.com, login, and then to DVR Preferences and confirmed that TRANSFERS and DOWNLOADS have been checked for it?

    Thanks for the response. I have "video sharing" and "enable video downloads" checked under DVR preferences, and I have Network Remote enabled on the Tivo box. Is there another setting I'm missing?

    I highly suggest you try out rebox.net or maybe video.net. Rebox is specifically designed to take almost any video and output it to os devices and android and does it quickly. Video.net allows more control and conversion options. Both include deinterlace or automatic deinterlace. If you are just goingto watch off your home server, you don't need to convert, assuming you have an okay processor and network connection, you can run something like vlc streamer or video stream from the app store and convert on the fly.

    That way you only convert the shows you want to watch and you can run it remotely. If you want to take shows with you and are going somewhere you don't have an Internet connection, you run rebox.net, if you are just going to watch them around the house or where you have a good Internet connection, then vlc streamer works good and you keep your better quality for when you want to send the shows back to your TiVo. http://www.clonead.co.uk/ is where video.net and rebox live, both are free. The streamers are in the app store.

    The only thing I can suggest is make sure that the TiVo can access the network, that the TiVo has the same IP address and MAK that you have in kmttg. Does pyTivo see the TiVo?

    Well bizarre. pyTivo was seeing the Tivo fine and I could send shows to it with no problem.

    It ended up working after I unplugged the Tivo and left it off for 20 minutes and plugged it back in. I had turned it off for a minute and plugged it back in and it still wasn't working. Don't see how it could matter how long I keep it off, but I found a thread in the Tivo forum where that was suggested to fix a connection problem for Tivo Desktop. Seems somehow the Tivo had flaked out and needed reset.

    Could have possibly been a network/IP address issue.

    Yes, Handbrake can handle deinterlacing (and inverse telecine [removing the 3:2 pulldown]). More likely than not, you actually need inverse telecining on your video, not deinterlacing. Most everything in the States is now shot on film (24fps) and then pulled down to 29.97fps for broadcast.

    At any rate, I built an encoding profile for kmttg that uses Handbrake to do this.

    hb_tivo_sd_crf - use this one for SD video
    hb_tivo_hd_crf - use this one for HD video

    They basically process video through Handbrake using the settings for Handbrake's High Profile encode. That includes the flags to inverse telecine and decomb. The profiles are quality based rather than bitrate targeted. The bitrate will vary depending on the quality of the input video stream, but the output are targeted to show consistent quality regardless of input stream.

    Well, I have been following the discussion for about three weeks, and I have downloaded the 116 pages, but to be honest I have not done a serious search for what I am looking for, so if this has been answered, my apologies, you can "boot" me out, yell at me, or if you're nice, point me to the right post. In my defense, I did have a surgery a week and a half ago that interfered with what I was trying to do, and the after-effects are still bothering me...

    So on to what I need to ask:
    1. Point 1: I only have to Series 2 TiVos with the plan to purchase a TiVo Premiere soon as I already have the Cable Card (my High Def TV has a slot for it, so that's how I watch High Definition programs -- mostly athletic competitions). I can not record anything in High Def.
    2. The TiVos have not been hacked in any way and the Hard Drives have not been upgraded in any way, but I am thinking of putting a 200 GB into one and a 160GB into the other one (they're laying around). That's besides the point.
    3. I have pyTivo installed. Works great for Getting Video from the PC to the TiVos.
    4. I have TiVo Desktop installed (almost 800 GB of Video in this archive now).
    5. I have Roxio Media Creator 9. In the past I had bought this, and had transferred the entire 1st season of Heroes on DVD with so-so success. To be honest, I don't really care to do that, as I since bought the DVDs for "Heroes", and that's my real archive there, but here's what happens.
    6. Occasionally, I fall behind on a series I am watching, like Burn Notice, so I transfer the episodes to the PC (I have specifically bought a 2 TB HDD for this). This allows me to save them and watch them later.

    What I need to know is this:

    a) What is the best encoding to use with KMTTG? (Especially since I just show a post discussing Handbrake sd vs. hd).
    b) I am planning to use pyTivo to then retrieve the episodes back when I am ready to watch them as I have always done.
    c) I'd love to cut the commercials out -- use VideoRedo for that?
    d) Is turning a file to an AVI make it smaller and maintain quality (since when I run pyTivo ffmpeg will re-process it back to what I need?)

    Basically what I want to do, in "My Video" directory, I want to have a sub-directory with "Burn Notice" episodes, and sub-directory with something else, etc.

    Does anything of what I wrote make sense?

    How do I do it the best way? Can someone guide me?

    Thanks!

    (PS. I love the program, I have used already, to save a couple of programs, but so far have not played with the output files too much, until I learn more).
