    Media Player Classic and the other players I've tried can't seem to pull it off. I'm going to install Tivo Desktop and WMP11 on my Windows XP Professional work laptop to see what kind of results I get there. Will report back in a bit.

    Well, at least I'm not losing my mind. I have just installed WMP11 on my XP Professional Laptop along with a fresh install of Tivo Desktop 2.5.1.

    Took one of the Tivo files that's on my desktop and moved it over to the laptop with a flash drive.

    Guess what? It has the exact same problem playing back on the XP machine that I was seeing on the Vista box. Thank God I didn't re-install windows over this issue. Also worth noting is that the laptop is using completely different codecs than the desktop, and yet the problem is manifesting in the same way.

    Now the only question is, is the problem in the Tivo Desktop software, or in the Tivo HD itself?

    I'm doing a fresh download of a known "problem" recording from the Tivo HD to see if that exhibits the problem too.

    Another possibility is that these problems are being caused by recordings made BEFORE the Tivo updated to 9.2. Will investigate that more also.

    I have 9.1, and now Tivo Desktop 2.5.1, and VideoReDo. In transferring an HD Tivo file to my PC, editing it with VRD, and saving as HD .mpg file when I put it back on the Tivo it has odd jumps & skips, i.e. missing video frames, though the audio always remains in sync.

    I have not tried (yet) saving from VRD as a .tivo file but will try that next--apparently VRD uses Tivos own .tivo directshow filters to function.

    But there's something about the HD .mpg files that Tivo doesn't like--maybe the non-standard GOPS? I suppose I could also have VRD fix the GOPS. The VRD developer is getting a Tivo HD, which if history holds true means they will get this sorted-out for sure.

    just set up ttg for my series 3 HD. after a little trouble getting it to show the programs available for transfer, it did. kind of. i have 105 programs. it lists the last 4 (including one being recorded right now and shows the others as "details unavailable". thoughts.

    also. i see a lot of talk about getting the 9.2 update. there's no way to "get" it, is there? it just comes from tivo when it comes, right?

    The "details unavailable" thing is usually a cache problem. Shut down TiVo Desktop and then delete all the files under C:\Documents and Settings\<username>\Local Settings\Application Data\TiVo Desktop\cache.

    You can sign up on the priority list.

    thanks windracer. that did seem to get more details (i now show 30-35 of the 105 programs), but i still can't see them all. I went into server-->tivo server properties-->performance and maxed out the cache size, too. but that didn't seem to get it done either.

    What's with the inordinate amount of shows that are flagged and not able to be transferred? For instance, Real Time with Bill Maher on HBO and many movies from HBO and Encore. What gives? TTG is great and all, but not if I can't use it!

    Complain to your cable provider... We're pretty much at their mercy, outside the local networks. But I can't see getting upset about anything on a premium channel like HBO being copy-protected.

    I'm having a strange problem (which may be the same problem HDTiVo mentioned earlier). I can transfer some HD programs from my S3 to my PC, but these half-hour HD programs off PBS are not working. When I initiate the transfer (either from TiVo Desktop 2.3a or using the direct download from the web browser) I get a 2MB file with (from what I can tell) no content. Does anyone know what might be going on?

    If the recordings are off broadcast networks. The cable company can legally protect anything else they'd like, unless prohibited by an agreement with the content provider.

    The cable providers mark content on some channels with a copy protection code called "Copy One Generation"; it allows you to hold only a single copy of the broadcast, being the one on the DVR. TTG and MRV need to make a second copy, so they don't work with Copy One Generation content. There's a discussion of this in the Copy Protection Affecting TTG thread.

    FCC regulations allow the cable providers to mark anything not in their core basic tier with that level of protection; other regulations require that they position all rebroadcasts of local television in that tier, so they can't apply copy protection to the national networks like ABC, CBS and NBC. Though the cable companies have been a bit too liberal in their use of Copy One Generation, premium service providers like HBO/Cinemax and Starz!/Encore explicitly want their content marked this way. You're free to complain to your cable company but it's unlikely to change that.

    The licensing for the protocols used to deliver the content to TiVo (DFAST and CableCARD Host Interface) allow the implementation of a "move" operation for Copy One Generation content which would make a copy, deleting the original recording when done. TiVo doesn't currently implement this.

    That does sound like the exact same problem - particularly because we both are seeing it on PBS HD recordings. Unfortunately, I only have those 'The War' recordings available to test. I should try some others on both my HD and S3 units.

    Do you have a second hi def unit to test MRV on? I found MRV worked fine. I also found that TTG didn't work on the program after it successfully MRV'd either.

    You have 9.2 on your Tivo, right?

    Some files wouldn't transfer for me with 9.1, but do transfer with 9.2.

    The Tivo just copies the original digital recording from your Tivo.

    These days, the encoders used by broadcasters and cable providers employ many 'tricks' to increase compression and improve efficiency. Many codecs on the PC simply cannot handle all of these. I do not like the MainConcept codec because it known not to correctly handle many high-definition transport streams. I much prefer the hardware-accelerated Cyberlink codec.

    MPG and .Tivo files may be set to use different video codecs -- depending on your PC's setup -- which adds to the confusion.

    In my case I have 9.2 on the HD the recording was made; but of course not when the recording was made. hmmmmm....


    The other recordings I successfully TTG'd were more recent ones.

    No, just the one S3.
    Yes, that's correct.

    Is it normal for TTG transfers (well, downloading via https://...) to go at about 1MB/s? That's pretty darned slow. At that rate, a standard HD 1 hour program would take over 1.5 hours to transfer. This is on a S3 Tivo, not a TivoHD.

    What kind of transfer rate are other folks seeing?

    *edit* Oops, I forgot to mention that I'm connected via Ethernet (100baseTx-FD).

    I realize there are a limited number of resources on this thing, but 1MB/s? I guess with two buffers writing to the disk at the same time, I'm lucky to get 1MB/s. Too bad there's no way to tell it to stop recording the live buffers. I'll try changing both tuners to SD channels to see if that helps. :)

    Yes, maximum TTG throughput on the Series3 is 15-17Mbps. You'll see different results with:

    1. both tuners set to channels you do not receive (i.e. no buffers);
    2. both tuners set to low-bitrate SD channels like SCI-FI and CNN; and
    3. both tuners set to higher-bitrate channels like CBS-HD and NBC-HD while watching a previous recording from CBS-HD.
    This is summarized in the sticky at the top of the forum.

    I TTG'd a recording I made from ABC HD under 9.1. While it did transfer - unlike those PBS HD recordings - it did not play in WMP. WMP said it was playing, but there was a black screen and no active progress bar...

    I ran it through VideoRedo and played the mpg just fine in WMP.

    The difference I observed is that WMP says it is attempting to download codec, then download codec failed, just before successfully playing the mpg (also other successful HD .tivo files do that) For this unplayable .tivo, there is no codec attempt.

    That is not the case from what I can see. I cannot transfer Travels to the Edge from 10/26 (again, this is TTG, not MRV).
