My understanding of playback via mplayer is, that mplayer uses its included 
synchronization logic.
That means it demultiplexes its input (evtually transforms it to mpeg-1/2), 
then synchronizes it, and multiplexes it to pes. That means the FF-Card 
receives a synchron stream.

I think moving that synchronizing logic out of software-playback devices into 
vdr will solve that problem (and also other problems like audio near cutting 
marks).

VDR however for now just forwards recorded data to FF-Card without ensuring 
any time-conditions.
