Problem with Nexus-S MP2 and BeSweet

[antiriad]

Is it possible to capture with Hauppauge Nexus-S TV-Card (digital TV), and convert it to divx/mp3?
I tried it, and had following problem:
I captured in MPEG, and demuxed a mpa audiofile with Gordian Knot (DVD2AVI). Then I encoded in divx4 (with the Gordian Knot) and got a perfect divx videofile. But when I tried to decode the mpa-file with BeSweet, i got following warnings (about fifty times):Stream Error:Sync found after x Bytes , x was a number between 2 and about 540.
The generated wav-file was about 3% longer than the videostream, and when I multiplexed it in the videofile, audio and video got more and more out of sync (audio played to slow, but played not linear slower).
Is the generated mpa-file corrupt, or is it another format?
Does anybody know a tool which can decode that mpa-file to wav or mp3?
WMP does not play the mpa-file, only PowerDVD can play it, when it is muxed in the videostream.
Please help. Thank you.

looks like your mpa file has invalid bitstream. there used to be a very similiar bug in tooLame when producing invalid mono streams (with lots of sync gaps of about 500bytes)
try to fix your mpa with BeSliced and post your logfile.
the result file should be playable in wmp.

Thank you, for your reply.

When I tried to fix the file with BeSliced, i got an error:
Run time error - Specified format doesn't match format of data.
When this file is corrupt - why does PowerDVD play this file without
faults?

i would highly recommed you to run your captured mpeg files trough pvastrumento first. it will correct any errors/problems in the stream if possible. you can also demux the sound directly and run dvd2avi only on the video file.
i never had any problems during encoding with besweet/vdub with this files.

I took PVAstrumento - and now audio and video is in sync.

Thank you Zhnujm and DSPguru, for answering and helping me.
