This appears to be a good thing to do.
I am, though, considering to rewrite the ringbuffer to make it store
individual frames rather than a big chunk of video. This would allow
stripping the audio packets in the _output_ thread rather than in the
input trhead, and might also help in hitting the right spot when
returning from fast forward/back.
I guess I'll know more about what I'm going to do with the buffer after
evaluating the DVD enhancements from Andreas...
