There was a long thread about a/v sync issues last week or the week
before. Basically I suggested running a Java app called ProjectX,
which will fix up your DVB file before you attempt to transcode it to
DivX or XVid (or anything else for that matter). It seems the current
linux tools people normally use do not completely fix the a/v sync in
the source file, so that any attempt to transcode ends in potentially
horrible a/v sync problems.
