I can't speak to video, DVD or blu-ray playback because I only use Myth to play recorded TV: OTA ATSC mpeg-2, NTSC SD mpeg-2 and HDPVR h.264. Nor can I speak to PAL or any other TV standard outside the U.S.

However, if the primary playback scheme fails for any reason, Myth will silently fallback to a working method. If your screen won't support 2X playback, it will fallback to 1X playback. If vdpau won't initialize, it will fallback to OpenGL, Xv or even shared memory. Some of those methods may not stress your CPU very much, so the only way to be absolutely certain what is going on is 'mythfrontend -v playback > playback.log' then dig through the resulting file.
