[MEncoder-users] Audio sync problems with HDV footage while performing an inverse telecine

It seems to be the -mc 0 causing the problem. Leaving in 
-noskip/-demuser lavf doesn't seem to have any affect but I'd like to 
avoid it breaking other files audio sync. What exactly would cause the 
encoder to skip frames?

Thanks again!
