possible damaged mpeg file?

[olly]

hi,

Not sure if this is the right forum to post in but....

I recently captured a TV broadcast in MPEG format at highest bit rate on my Hauppauge PVR, i think it is at 12MB/s, and the file was a couple of hours long. I split it into 2 pieces using nanoPEG Editor 2.2 (provided with Hauppauge software) to author to DVD with TMPGEnc DVD author. TMPGEnc author didn't like such a large file as it couldn't make enough VTS titles to accomodate it. So I split these 2 files in half again, basically leaving me with 4 mpeg files, 2 to be authored into each DVD project.

Now, the first two authored no problem, the problem came with file 3 and 4 when TMPEnc would only author about 600MB or so of a 9GB DVD then give up - so I figured that the 4th file was ok by authoring it alone, so basically I have one file that I think is corrupt.

I have tried to demux it using TMPGEnc MPEG Tools, but again it only demuxes a small amount of the file before giving up - not with errors, but just finishing the process early. I also tried re-encoding the file with TMPGEnc, which it does successfully - but the resulting file basically stops after 5 mins and is just locked on one frame for the rest of the duration of the movie.

So apologies for the long post, but to cut a long story short, I have an mpeg file that plays OK in Media Player Classic, but I can't do anything with it i.e. demux,author or re-encode. without it giving up part-way into the file.

Does anyone have any suggests I could try to repair this file into a state that I might be able to author with TMPGEnc Author?

Thanks

tried demux with projectx?

or maybe try repair with videoredo.

Thanks for the advice - spot on - demux with projectx done the trick.

Looks like videoredo didn't help, it was outputting empty file like the other processes I tried.

At first I thought the *.m2v that projectx gave me was out of sync with audio, but when authored with the *.mp2 as audio stream it turned out perfect.

Thanks again
