Ed,

Tried the patch to see if it would fix my OSS prebuffer/ ALSA Av sync
issue but couldn't get it to compile.
I get an error compiling transcode. An include missing? Tried adding
audiooutputbase.h but that's not it.
This is wat I get :

g++ -c -pipe -Wall -W -O3 -march=pentiumpro -fomit-frame-pointer
