Is this on absolute frames, or video frames?  If the 3-5 types are based
on th number of video frames, then this really simplifies the problem (no
need for the extra table at all until mpeg2 encoding is supported).  If
they are based on total # of frames, it is not so easy, since there is no
gaurantee that we'll build the same number of audio + sync frames as the
original had (we do gaurantee a 1:1 mapping of video frames though).  A
quick look shows it is based on framesPlayed, which I believe is the
number of video-frames, so it should work fine.

Thanks!
