How do I play H.264 recordings transferred via KMTTG on my PC?

    Comcast is switching most of my channels to H.264. I just transferred The Walking Dead to my PC and used the "decrypt" feature like I always do. When playing it back using VLC, I can hear the sound, but there is no video. Is there an additional step I need to take when transferring H.264 recordings?

    You have to use transport stream mode when transferring H.264 video.

    Enable following under configure--Program Options
    * Download TiVo files in Transport Stream format
    * Decrypt using tivolibre instead of tivodecode
    * tivolibre DirectShow compatibility mode

    Why this one? Is it just a requirement for H.264 decoding? Or suggestion? I've never had it enabled, but I just get MPEG-2 from CableOne (and OTA).

    I'm unclear despite reading the bubble help for the two DirectShow-releated Program Options.

    This makes the tivolibre decryption identical to what DirectShow Dump decryption would be instead of trying to do some tivolibre specific fixes. There's been some feedback in tivolibre thread that this leads to less glitches during playback when there are issues with the downloaded recording.

    Another question. Do I still have to use transport stream mode on H.264 recordings if I am only transferring the shows for archive purposes and I plan on serving them back to my TiVos via pyTivo?

    Cool, and I assume I should turn transport stream mode back off when transferring non H.264 recordings such as the locals?

    Not necessary - mpeg2 downloads can be TS container as well.

    I was under the impression that there could be some undesirable side effects when using TS. That's why I've never used TS to transfer shows in the past.

    Unfortunately, I've found that that option doesn't work at all. I had to try and transfer an episode of "Bates Motel" and an episode of "Blindspot" last night. Comcast made A&E H.264 (and with an alarmingly low bitrate of 2.5 megs, but it looked really good) while NBC is still MPEG-2. "Bates Motel" was watchable, while "Blindspot" was just one hour-long green screen, as if there was a bad frame somewhere.

    I've found that I actually have to switch off the TS option if the channel isn't H.264. So far, only A&E HD and FX HD are switched over, and the only way I know it is if the download constantly fails about 200-500MB into it.

    I downloaded 2.1r last night, hoping that would fix the issue, but it doesn't seem to have done it.

    What player are you using? If Windows Media Player then could be a codec issue. Try playing with VLC instead for example which has its own built in codecs.

    It's actually going directly from kmttg into VideoRedo or TMPGENC Video Mastering Works 6.

    The problem happens every so often, and I suspect it's something Comcast is doing. I find it helps to use Tivo Desktop to download all but the H.264 streams. Usually if the stream's bad, it'll refuse to download it at all.
