    I strongly recommend the VideoReDo software VideoReDo MPEG Video Editor
    I purchased it recently and it works great with the pyTiVo software. I know they have a trial period so you can give it a try.

    Also, try to transfer your shows when you are not doing much on your network. You can also put your TiVo in standby to help before you start the transfer.

    If you're comfortable with the command line, I use ffmpeg. But before converting I would view the decrypted video and verify there is sound alignment.

    What OS are you using?

    Is the sound out of sync for the entire video or does it go out of sync part way through?

    Is the sound out of sync when you play the .ts file before converting to .mp4? How about when you play the .tivo file (pytivo doesn't save the .tivo file if it is decrypting so you may have to download again)?

    Was your download error free?

    I had sound syncing problems (starting partway into the video) after converting with VideoRedo this past spring. It was due to some unexpected bad data in the original .ts. I reported it and the VRD team figured out a way to detect and skip that bad data (I suspect they might describe the problem and solution slightly differently), so that the version of VRD I'm using now doesn't have that problem.

    Running QSFix on them might help.

    maybe don't convert it to the mp4 format? All I need to do is decrypt the .TiVo files. And plex works with the resulting format.

    Thanks. The videos are on a HP home server and don't stream smoothly in the TiVo format. The MP4 format streams fine but voices lag video.

    After my .TiVo files are decrypted, they are in the TS format. Which I can play in Plex without any audio or video issues.

    Figured out why my .TiVo files weren't streaming right. In Plex, I had changed setting to automatically convert videos, rather than just use original. Once I changed to use original, files stream fine. Thanks for the help.

    Issue with aspect ratio; not sure if it's this pytivo or the bolt as I switched to them around the same time. I use handbrake to rip and store as mp4. When I transfer to the bolt and the bolt is set to "full" it fills the screen, but the people are kind of narrow and when I change it to "panel" I get huge letterboxes and they become a little fatter. When using handbrake I've tried a couple of the preset options; Fast 1080p30, Fast 720p30, Fast 480p30...all the same.

    Anyone else with this issue and a bolt?

    1080p and 720p should always be full screen and the adjustment option on the TiVo shouldn't even work. The other one is SD and will need to be set to "full" to work.

    Also for NTSC video the proper frame rate is 29.97 or 59.94*, don't use 30 or 60. I'm not sure how the Bolt handles those and at the very least it will have to adjust them during playback which can cause jitter.

    * Might be listed as 30/1001 and 60/1001 instead of 29.97 and 59.94.

    From the description, I think he's looking at 2.35:1 widescreen video, encoded without letterboxing. In which case, "Panel" is the correct setting, and he should expect/accept letterboxing by the TiVo. On the other hand, if he chooses "Zoom", it should have the correct aspect ratio AND fill the screen... but the sides will be cut off.

    Hmm, so the TV stations the TiVo records are going to be either SD (480i or 480p vertical resolution I think) with a 3x4 aspect ratio, or HD (720p or 1080i vertical resolution) with a 9x16 aspect ratio.

    The TiVo's Panel/Zoom/Full control only works for SD recordings.

    So what you're telling us @wmcbrine is that other aspect ratio recordings transferred to the TiVo via PyTivo are treated by the TiVo as SD recordings?

    I wonder if pytivo transcoded @Test's video and if so what the ffmpeg command was. If the debug setting is on, that should be written to the log file.

    Incorrect. The controls work for anything that doesn't match the display's aspect ratio. This is easiest to see with 4:3 recordings (or live TV) on a 16:9 set -- or with 16:9 recordings on a 4:3 set. But it applies just as well to 2.35:1 recordings on a 16:9 (1.77:1) set.

    No, not at all.

    P.S.:

    16:9 SD is also a possibility, increasingly common nowadays (e.g. on broadcast subchannels). 16:9 DVD rips sent to the TiVo are also SD. Note that these all respond (or fail to respond, depending on the aspect ratio the TiVo thinks that the TV has) to Zoom/Panel/Full in the same way as 16:9 HD recordings.

    It would be better not to think of resolution and aspect ratio as being coupled, because they really aren't.

    Yeah I over simplified because I thought you were encoding TV shows from the TiVo itself. If you're getting videos from the internet then all bets are off, the aspect can be all over the board.

    Thanks for the correction, I learned something new. It makes sense.

    So I think this means the modes work like:
    Panel - Scale to fit entire video in the display maintaining the aspect ratio (centered) w/ letterboxing on the left/right or top/bottom as needed
    Zoom - Scale to fill the display maintaining the aspect ratio (centered) w/ clipping of the left/right or top/bottom of the video as needed.
    Full - Scale as for Panel, then stretch the video as needed to fill any letterboxed area (does not maintain aspect ratio, perfect for anamorphic dvd encoding)

    So for a 1:2.35 encoded video (aspect ratio of some movies); On a 16:9 display; Panel will show the entire video in the correct aspect ratio (with letterboxing top/bottom; Zoom will fill the display with the video clipped on the left/right in the correct aspect ratio; Full will fill the display with the entire video but will vertically stretch it making things look tall and skinny.

    That is a really good point. I usually don't but I must have been thinking the TiVo ONLY deals with TV and it makes that assumption. And that was bad on my part, it doesn't deal with ONLY TV and it doesn't make that assumption.

    I'm not sure about this but it may be that we have differing definitions of SD? When I rip an anamorphic DVD the resulting video aspect ratio is 9:16 not 3:4. I've been thinking of SD as 3:4 video at either 480i or 480p. If the defininition of SD is video at 480i or 480p any aspect ratio, then yep that's what you'll get off of a DVD, and I agree with you.

    Never-Hydra Roamio Basic
    Win 10 PC
    Just installed PyTivo

    1. Roamio Can get a jpg
    2. Roamio can Not get a mp3
    3. Roamio can Not get a .tivo

    All are in c:\TestAtRoot\
    Don't see any differences in permissions between the files, but there is a big difference in sizes, KB vs MB vs GB.

    The basic goal is to backup the Roamio. And occasionally restore a show to the Roamio when there is nothing else to watch.

    jpg appears on the screen okay.
    mp3 A problem occurred while accessing the server. This may be a temporary problem....

    My Shows has a orange ! point
    Select brings up PC : My Videos Root
    Then Red X
    X NBC Nightly News with Lester... Thur 12/7
    Selecting that brings up further details. Again with a red X.
    X This recording will be kept until you delete it.

    Is it possible to restore a .tivo file ?

    Any suggestions ?

    wmcbrine is right in I can press zoom on an HD channel and get, zoom/panel/full.

    I'll have to mess around with the bolt setup when I get home, because I streamed the same ripped DVD program from the bolt to a mini last night and it looked fine.
