Interesting datapoint: If you run RealPlayer7 for Linux under FreeBSD,
audio and video are desynchronized.
If you reconfigure it to use the "Old OSS Drivers" instead of "Native
Sound Drivers" it works just fine (but fails to provide audio when viewing
ShockWave content).
This is with a SoundBlaster AWE64 ISA card.
... which is to say that our sound drivers are already *capable* of
avoiding the annoying out-of-sync buffering bugs, but they usually
choose not to :-)
