It won't work. Apparently MPlayer needs exact timestamps for all packets (even 
when it is for a continous audio stream - the only thing MPlayer supports btw 
afaik). So either there is an average ~100ms desync between a-v, or the 
demuxer calculates a timestamp for every packet (not just those at the start 
of a page). For this task the demuxer needs some information only available 
to the decoder - numer of modes, blocksize used in each mode. A clean 
solution for this is imho not trivial.
