On my machine the switch to libavcodec made divx playback on the dxr3
alot faster but the output quality was not as high. I know you disagree
to both of those statements, but you are welcome to come see for
yourself. The difference is noticeable...
I was going to do some sse stuff to libavcodec but I noticed Michael
beat me to it, which was probably for the best anyway ;).
