    I have the latest Tivo update and I still don't see captions after making a round trip with a .tivo file. I'm also using the latest versions of kttmg and pyTivo.

    I just confirmed again it worked for me, but I know why. I have kmttg configured for TS downloads. So if you download TiVo files in Transport Stream container instead of Program Stream the captions are preserved. Of course the trouble with TS TiVo files is "tivodecode" does not work reliably with them, however in my case I use VideoRedo to decrypt TiVo files so it's not a problem. However if you are just storing them as .TiVo files on your PC then using TS downloads will solve your problem.

    P.S. I did try downloading same clip in Program Stream format and confirmed the captions are not preserved that way, so that bug still exists.

    I'll have to try that option. It would still be a hassle for me as I want the option to decrypt the .tivo without using VideoRedo which costs $50.

    You say tivodecode does not work "reliably" with them.. I thought it didn't work AT ALL with them. Someone (hopefully not you) said that there was a patched version of tivodecode, but I couldn't find it in searching a few weeks ago… (and I asked on the tivodecode source page, and nobody responded)

    I believe the kmttg windows package contains TS tivodecode binary and the source are available via kmttg as well:
    http://code.google.com/p/kmttg/downloads/list
    It works for some recordings but not others. I recently tried it on a couple of H.264 TS .TiVo files and it worked fine. But I have several clips for which it does not work.

    I just did some tests, and what I saw here is that captions were preserved when extracting program streams, just not when sending program streams back. So, you can do this:

    1. Extract and tivodecode the file as a program stream.
    2. Send the file back as a transport stream -- you can do this with pyTivo by setting "ts = on" in the server section of pyTivo.conf.

    When I did this, the captions were preserved, except for a few missing letters.

    Thanks! I'll try it. Though I probably won't be able to until next week.

    Well, people are reporting tivo to tivo and tivo desktop doing the same thing.

    What KMTTG does is use the exact same HTTP url to grab, restore shows as Tivo desktop does.

    The fact that tivo to tivo does it to is a real problem. Sounds like something was forgotten in new xfer code.

    KMTTG is not illegal. The transfer to a pc to store for future use is perfectly the same as Tivo desktop.

    Kevin, does kmttg store the ts vs ps download config by TIVO? I ask because I have a premiere and 2 tivoHD. THe TS stream download/Videoredo is fine for a premiere, but TS streams are not reliable on TivoHD, correct?

    So it might be good if the ts/ps downloads would be by tivo

    No, it's a global setting. I'm not aware of any differences in TS download reliability between series 3 & series 4 models, but I don't download from series 3 units anymore.

    I am fairly certain that the captions are clipped/jumbled during the remux to download the video off the Tivo. The text seems to go missing in 2 character chunks and sometimes those characters are simply moved elsewhere in the sentence.

    AFAIK, the ts downloads were broken for quite a while on Premieres. This was from the pytivo (wmcbrine) group. And these were recently fixed.

    My assumption is that since TivoHD units have not had an update in quite a while, its TS download would still be broken, but I could be wrong.

    That's news to me and not my experience. Since I use VRD which can decrypt TS TiVO files without a problem I've been using TS downloads for at least a year without issue. I mostly advise against it for anyone that doesn't have VRD since there are still issues with tivodecode for TS TiVo files.

    You've misunderstood something. There are (still) some issues with TS, but it was never "downloads are broken".

    TS transfers only work one way (TiVo -> PC) on Series 3. And it's annoying, because the S3 pretends it can receive TS, and requests it, but if you actually send it, it barfs.

    Ah, that was what I 'misremembered' :)
    It was uploads are broken to S3 units.

    I have been trying to pull several 30 minute HD shows back to my Tivo Premiere after cutting the commercials with VRD+. I want to preserve closed captioning. I have configured "ts = on" in pyTivo.conf, and the shows transfer fine. They display the closed captions when played back on the Tivo, but, the 19 minute commercial free shows only show a duration of 2 minutes (partial) and, when the shows are played, I can only FF to the 2 minute mark before the playback pauses. The progress bar only shows 2 minutes of green out of the 19 minutes of video.

    If I press play, the playback resumes and I can view beyond 2 minutes into the show, but, the progress bar never moves beyond 2 minutes. FF seems to work, but REW restarts the playback from the beginning of the show.

    If I push the shows back using pyTivo and kmttg, the show duration is correct, the progress bar advances properly, but CC is not preserved.

    Is this only a Tivo Premiere issue? If I transfer the shows to my TiviHD, will CC be preserved? If I then transfer the shows from the TivoHD to the Tivo Premiere, will CC be lost?

    Funny coincidence, last week my Tivo Premiere's software was upgraded. while transfering a edited toasted tivo tv program, the tiVO was recieving a download from Tivo with the Tivo tutorials at the same time. Low and behold, the CC worked on the uploaded edited program to my premiere. Thought, yea they fixed it, but alas, just this once. I didn't watch it all the way thru yet.
