This offers better quality as the version on youtube, because youtube reencodes the video after upload, so there is a quality loss.

It's a mkvContainer with h264/AC3 streams. You can play this file in VLC or in directshow based players (like wmp, mpc, ...) after installing ffdshow and Haali Media Splitter.
