So I've compared a few programs, Terminator 3, Olympic and American
Idol. There is huge difference in the number of buffer
allocated. I'll include what I think is relevant here, but I'll
save the log for later. The only one that play fine is Terminator
3 which uses 65384 KB buffers. That's actually the only stream
that works on my box right now. So is it possible that this
buffer management isn't working properly or the buffer aren't suited
right? Who can bring the attention of this to one of the
developper (if not reading, and if my info is relevant)?<br>
