You need DrFFMPEG from DrDivX. It's not based on latest SVN from FFMPEG 
but rather a version from a few months ago. We plan to merge many 
changes into DrFFMPEG soon.

DrFFMPEG will work in MSVC8 (and VS Express) in Debug, Debug ASM and 
Release. There should be a "Release ASM" but we don't use it. The ASM 
uses something called libavdsp that is built with gcc as a DLL and 
includes all the ASM stuff in i386. So it should work with a Release 
build too. Otherwise you just have no ASM acceleration.
