Problem With Sound After Transferring to TiVo

I went to transfer an old mpg file from my PC to my TiVo Series II. While it was transferring I started to play it and it was play fine but I noticed that the length of the video was showing as 10 Minutes whereas it was over an hour.

I stopped the transfer and ran the video through quick stream fix. I checked it on the PC by using Windows Media Player.

I then started the transfer again and started playing it. The length showed correctly but there wasn't any sound.

Other videos transfer fine with sound and video working so I don't think it is a problem with pyTiVo.

The file information from before and after running it through the quick stream fix is shown below. Except for the size it appears to be the same.

Any suggestions on how to get the sound working for this video would be appreciated.

It's the stream ID. TiVos require AC3 audio to be on Stream ID 0x80. Unfortunately there is no way to change the stream ID in VideoReDo. You'll need to use another program to demux and remux the audio and video so the audio is on 0x80

I don't know, it shouldn't have. TiVos only work with AC3 on 0x80. Did you use pyTiVo to transfer it? It might remap the audio stream ID.

OK next save the file again but recode the audio to MP2. This will tell us if the audio is actually the problem or if it's the video or muxing causing the issue.

I have never done anything special to get my TiVo movies to work with VideoReDo. The only difference for me (between it working and not) that I can isolate is that I am taking a TiVo Premiere video now versus a Series II.

Anyway I have done the following to correct this to no avail:
Increased the "Number of frames in the ... buffer" sizes to 1024 for video and audio.
Failed to locate the setting "Allow multiple audio streams"
Ran the QuickStream Fix for the video.
Tried to Save As an MPG video and it has the "Audio Ring Buffer Overflow" every time.

One thing to note though... in all tests I have done with the 'same' project file I originally created it from the .TiVo file then after the QuickStrem Fix I kept the same project file and did not recreate it (pointed project file to new input file...)... Was that problematic? NOW I just opened the original fixed MPG (not project) and remuxed the entire file (both the original and the QuickStream fixed one) and it seemed to work. One change here I just did is set the Win7 shortcut to compatability for WinXP.

TiVo Remux status:
Audio frame errors: 26
Input Sequence Errors: 304
Video resync frames removed: 1529
Video output frames: 537543
Audio output frames: 280251
Processing time (secs): 104
Processed frames/sec: 5155.99
Actual Video Bitrate: 11.43 Mbps

QuickSteam remux status:
Audio frame errors: 3
Input Sequence Errors: 1
Audio resync frames removed: 3
Video output frames: 537529
Audio output frames: 280243
Processing time (secs): 251
Processed frames/sec: 2133.41
Actual Video Bitrate: 11.43 Mbps


In both cases the audio is present and seems to work. I jumped ahead and the audio and video are in synch.

I am now going to re-edit the QuickStream Fixed version and try saving the edited version to see what happens and will report the results here.

I just wanted to say that I bought the upgrade to VideoReDo TVSuite v4 and all works perfectly.


THANKS!
