    Your right! I guess we'll have to wait for the Tivo update to fix the upload problem. I downloaded the new 2.6 version of Tivo Desktop and the same programs that failed previously failed again, and at the same place in the file.

    Slower...
    I heard it was going to be after the superbowl. :) A specific month wasn't given was it? TD 2.6 was promised and delivered in March.

    Release 2.6 does not fix the problem. Programs that failed previously to upload from Tivo continue to fail at the same point of failure as with release 2.5

    Because the problem is not with TD.

    I was able to get this to work last night. Thanks for the advice. My only issue now is that I have .tivo files which I want to get to Mpeg4 format (high quality). Any advice as Visual Hub doesn't seem to handle these.

    In recent days, some people have reported that they have been upgraded to 9.3.

    I was directed to this thread by another poster, so I'll reiterate my issues here.

    Unlike a lot (all?) of the posts in this thread, I'm having issues sending large files TO my S3. I have a lot of PAL-encoded content that I am transcoding to 1080i NTSC MPEG2 format with a professional transcoding software package, then transferring to my S3 for viewing on my big screen.

    The uploads go fine when the show is about an hour long, and is about 6GB or so of content.

    However, if the file is larger, say 17GB or so (2 hours,) the transfer never gets past about a seconds' worth of data down to the S3. I have verified that this is not a firewall issue (disabled,) a network issue (hardwired through a gigabit switch, and if it was a network issue, the 6GB transfer wouldn't have gone,) and have rebooted the S3 multiple times. If I select the "view while downloading" option when the download has started, Tivo comes back with a "transfer interrupted" message almost immediately. This is a S3 with about 1TB of free space, so it couldn't possibly be a space issue.

    Do we have some kind of hard limit on the file size that can be uploaded?

    TIA,
    -P

    pmrowley,
    Sorry I misunderstood your post, I thought your problem was TiVo to PC, and that is why I directed you here. I guess I didn't read closely enough and I apologize.

    All the right people to help you out, do participate in this thread, so you will get the best help available, even if they choose to answer in your original thread.

    Richmond,...
    I haven't posted here in a thousand years, but I am having similar issues. I haven't done exhaustive testing, but for me every show recorded on NBC-HD fails in the first minute or two, transferring 15 meg of a multi-gig show. The exact byte counts differ by recording, but it stops at the exact same point for a particular show no matter what method I use to transfer the show.

    As best I follow this thread, the conclusion is that we are waiting for some future TiVo release and there is no workaround. Sound about right?

    I'll add my experience with this problem which is that I'm unable to download most of the HD PBS series 'Nature' and 'Nova'. I've had success transferring HD content on other stations.

    What's your secret?
    I can successfully transfer and play SD home movies in .wmv. I've been trying to make some HD home movies and transfer them to Tivo. They play but the images are too large and are chopped off at left right and bottom. I encoded them in .wmv @ 1280x720. I tried scaling them down but they looked exactly the same. I tried all the aspect ratio controls I could find on my TV and Tivo. I also tried .mov. I was going to try .avi but the file is WAAYYYY too big. I should add that these are screen captures from Camtasia and use the TSCC codec.

    S3 and Tivo 2.6

    Well, I finally have some data, not much, to supplement the above. Using various HD and LoDef broadcasts of this show, I've found that:

    • except as noted below, transferring the HD versions from Tivo to PC have all failed at the same point, right at the beginning of the show. (5 different HD broadcasts of the same program)
    • transferring LoDef versions of the same show (2 broadcasts) from Tivo to PC have been error free
    • transferring one HD version that I set up to record manually, +5 minutes after the show's scheduled start, proceeded without incident, to completion.

    I continue to think that, at least in my case, the failures are the result of some embedded start of program (or end of program) code in the file, and that the one iteration I was able to transfer successfully did so because I started it 5 minutes late and so bypassed the problem code. Although I used the Clapton Crossroads show for my testing, I have had other programs from different HD channels that have behaved the same way, e.g., Etta James on Austin City Limits. The transfers fail without error messages, 1-2 minutes into the recording. Tivo Desktop seems to think they've completed but in actuality, the files are very small and only iinclude the first minute or two of the program.

    So when you set up an HD program to start five minutes early the resulting recording transfers to your PC without a problem (assuming you're using TiVo Desktop)? Have you been able to replicate that? If so, that's very good information and would certainly support your theory of problematic data being located at the beginning of a program.

    I haven't been having any failures of late, but I'd be interested to hear the results from anyone else that has with trying the +5 min. work-around.

    > when you set up an HD program to start five minutes early <

    Rich, no, I think he meant 5 minutes late, not early. Thus skipping over some problematical marker embedded in the stream at the front.

    To do so, you have to set things up manually, because the padding feature only works in one direction (unfortunately).

    Ohhhhh. Got it, thanks for that. (I have to stop reading these things so late at night. :eek: ) That makes more sense. I was having a hard time figuring out what data might be generated at the start of a program which wouldn't be there if you started recording earlier (unless TiVo was injecting something at the beginning of each recording.)

    So could you start it one minute late and get the same results? Or what if you did start it five minutes early? Is it data generated at the end of a previous program as the OP suggests? Or is the issue one to two minutes into the new recording because the OP's files fail at that point? :confused:

    Whatever the case, this is good info and might narrow down the cause of at least some failed transfers. I wonder then why some are seeing this and some are not being that we're all on the same software version. Something that the local cableco's are generating?

    That's right, 5 minutes late. I'd try 1 minute or, better, 2 if I could but the manual start that I was referred to here is in 5 minute increments.

    It looks, basically, like it's at the top of the hour, at the point at which program 1 transitions to program 2. It seems to catch a snippet, less than a minute, of the upcoming program, the one I want to record. End of program, stop code, seems more likely given the symptoms. I virtually always set my recordings to start on time, never (or very rarely) early.

    I'm going to try to replicate it with a couple of the other programs for which transfers have persistently failed and see if the same thing happens.

    Thanks for following up on this and giving it a few more tests. :up:

    Is it possible it has anything to do with switching tuners? I know when we record two programs back to back on the same channel, TiVo's current software causes it to switch tuners each time rather than staying on the same tuner. IIRC TiVoJerry said that the next upgrade would remedy that situation. Just wondering if it has anything to do with that?

    Tim,
    > That's right, 5 minutes late. I'd try 1 minute or, better, 2 if I could but the manual start that I was referred to here is in 5 minute increments. <

    The base values are in 5-min increments, but you can use Options to then start 1,2,3, or 4 minutes early, from that 5-min delayed base. Thus obtaining a net 4,3,2,1 minute delay from the real start.

    Rich,
    nope.

    okay, since I've upgraded desktop 2.6 no more partial recording problems so far. However, Now around the 20 minute mark into my programs the progress bar on wmp11 reaches the end and I loose all navigation ability even though the show will keep playing. Anyone seen this?
