	Therefore, I don't really need to worry about it for an audio
packet? Or, if it's not too much trouble to calculate, should I go ahead
and put it in? And I still need calculate the PTS for video frames,
regardless? That's no problem.

	So the RoQ audio is DPCM-encoded which basically means number of
bytes in a chunk is equal to the number of samples. So I just divide the
running total of audio bytes by the sample rate (22050 Hz)? And I need to
further divide that by 2 in the case of a stereo block, I trust?

	Thanks...
