Hey All,
I might be fighting a losing battle but here goes.
I have about 30 VCD episodes of a certain "Trek" series ;)
I am trying to author them onto DVDR (aren't we all)
I am using an mpeg1 21 minute file as my test case before trying the 1 hr shows

I use TMPGenc to simple demux the file
I use Besweet to convert the mp2 using the'DSPguru_MP2_for_DVD'profile
I then used Tmpgenc to simple mux the file back
Result: At 20 minutes the audio was between 1 and 1.5 secs out of sync

Besweet Logfile:
BeSweet v1.5b15 by DSPguru.

hmm... the logfile shows that there are no errors in the stream, so you just need to find a way to extract the a/v delay value of the original (s)vcd.
