My AMD Athlon 64 3000+ (2 GHz) manages to play this video at a very
acceptable framerate. I assume there are framedrops (100% CPU load) but
the image is quite "fluid" (something like 20 fps, wild guess).

There is a libtheora-mmx branch in svn which may have even better
decoding speed. I use the normal libvorbis-alpha4 (I don´t know if it
has any SIMD code).
