Problems like this - where media players can play audio and video streams separately, but not together - are often caused by the 'presentation times' (i.e, the "fPresentationTime" values) of the two streams not being properly synchronized.

You should make sure that the "fPresentationTime" values for each stream are accurate, in sync, and are aligned with 'wall clock' time (i.e., the time that you would get by calling "gettimeofday()").
