[MEncoder-users] a-v synchronization problems of some NTSC DVD with -oac copy ADDITION

[David Soukal]

I apologize, the log fragment I posted is from the 1st pass with lame
encoder, so there's so A-V information (all zeros). The log from the
second pass looks like:

So there's some A-V correction being done already. But this should not
necessary be a bad thing, right?

Thank you.
