    I'm able to download the full file in TS (it hangs at the 200mb mark but then continues), but decryption won't work and I can't get the .Tivo file back on my Tivo using PyTivo. So I guess if you have a download that doesn't work you're just sorta screwed?

    You should be able to use pyTivo to transfer back TS .TiVo files. It's likely you have an old version of pyTivo which is why that is not working - update to latest wmcbrine version and it should work.

    I just downloaded pyTivo the other week. When I try to pull the .Tivo file the Tivo says "Transferring prohibited by the copyright holder." I'm not sure why because KMTTG otherwise lets me download and decode said video (although the download quits early). If I try to push the file I get an "unsupported operand type(s) for /: 'str' and 'int'" in pyTivo.

    pyTivo pull should work without trouble.
    Probably should move this discussion to the pyTivo thread, but how did you install pyTivo? If you used the Windows installer that version is horribly outdated and should not be used. Follow Windows_Install instructions for a Windows install.

    I installed following the windows install instructions (I didn't even know there was a windows installer) and then pointed everything to the correct directory and used the KMTTG components. The transport stream problem is really a secondary concern of mine (since I'm only using it to get a show that fails to download) so I'll post over in the pyTivo forum. The main issue I posted here was why I couldn't transfer mp4 files using pyTivo. I thought it may have been an encoding issue, but it plays fine on my PC...so perhaps that is also a pyTivo issue (although I can transfer mpg and mp4 files encoded with ff_ipad no problem)

    You might try an diiferent version of ffmpeg.

    moyekg:

    Thanks for that. I followed the instructions but when I try to start the service I get an error: logon failure. I'm really shooting blind here. I typed Administrator in the "This account" box and filled in my admin password but no go.
    Any ideas?

    The kmttg service login should be your normal Windows login account name, not "Administrator".

    Possibly a dumb question, but: if you can successfully emulate an MRV transfer then wouldn't this also work to transfer shows that are "protected" with the CCI Byte problem? Just MRV it instead of TTG'ing it?

    You can't MRV a protected show either. Only MRS it.

    Ah, that makes sense. I've never used MRV or MRS, so I wasn't aware of how it worked. Thanks.

    Can you download these and then transfer them *back* to the Tivo for watching? i.e. just to offload them.

    Sorry for another repeat -- I have sort of the same question for .Tivo files in PS format. I tried doing that a week or two ago, but it didn't show up on the Tivo when I browsed my Tivo when running pyTivo on my computer.

    If someone figured out how to emulate a TiVo on the PC side, sure, but AFAIK that hasn't been done. (MRV is initiated as a pull, so a TiVo would have to think the PC is another TiVo for it to be possible). If you mean just transfer them back as if they were a normal .TiVo file, no, that doesn't work.

    More relevant question for pyTivo thread, but all .TiVo files (PS or TS) can be served up by pyTivo, so not sure why some seem to be having issues with that.

    pyTivo can send back both PS and TS .TiVo files (via pulls -- pushes require decryption). pyTivo uses FFmpeg on .TiVo files, as on other files, to check resolution, duration, etc. Sometimes, this process fails, in which case the file is marked with the copy prohibited symbol, as with any failure at this stage. If you really want to ensure that .TiVo files pass through this stage, you can disable pyTivo's use of FFmpeg, and it will just blindly send anything with a ".TiVo" extension. I would instead suggest using a more current FFmpeg, which should handle .TiVo files better, although not necessarily (there have been regressions in the past). (Note that FFmpeg can't actually process the encrypted files, but it can (usually) read them well enough to collect the basic info, because .TiVo files aren't entirely encrypted.)

    OK, that explains it then. I used to use ffmpeg as well to examine .TiVo files in kmttg as well but got several reports of problems with that, so since have switched to use mediainfo CLI (kmttg Windows tool package includes binary for it) which works much more reliably on .TiVo files.

    A wierd problem has developed here.

    I almost always use VRD to encode with kmttg.

    Today, I tried taking some HD files from my tivo premiere 4, decoded to mpg (tivodecode), and they looked and sounded fine.

    I tried to use the ffmpeg tivo_hd, as recommended here as a test and the video is still fine, but the audio seems off about 1.5 seconds all the way through. If I use H.264 MP4 (A VRD encoder profile), it looks almost as good with sync'ed sound all through.

    I did about 6 videos and they all did it

    I seem to recall this problem before I got VRD, so is it known? I'm not doing anything special in the rocessing.

    Unless you run "QS Fix" step as part of the flow sync problems are quite common when re-encoding.

    Ah, thats what it was. And VRD does the qsfix during transcoding too

    Thats what it was. So QSFIX happens also if I say to tivodecode using VRD too, correct? So I can download and then QSFIX decode using VRD, then run ffmpeg on the resulting mpg file outputting to mp4

    Correct?

    Yes, if you turn on "Decrypt using VideoRedo instead of tivodecode" option then kmttg will automatically do the QS Fix when "decrypt" task is enabled so you get decrypt + QS Fix in 1 step.
