Dual cores are useless with VLC for H264 decoding.
It will remain like that until ffmpeg (program used by VLC for H264
decoding) use multiple threads (and i don't know when)).

Then it must be using a directshow proprietary codec (i sup
pose you don't use vlc on windows)

There is absolutely no way, even with other programs, they _all_ use ffmpeg.
