I guess what I meant to ask was :  so mencoder's mechanism for keeping 
synchrony doesn't always work and disabling sometimes keeps sync?

So even if I get 1 duplicate frame (which seems to be case, in all my 
videos), it could still be in absolute sync?

How is it that the A-V sync info is not always an indicator of sync?

I apologize for the questions, but I like to know how things work.   And 
thank you for your patience.
