ZVISION: Change screen resolution for the hires DVD videos to 800x600

Also, this hooks up the MPEG-PS decoder, but only if libmpeg2 is
compiled in. The DVD videos are still disabled until AC3 audio support
is implemented.
The hires DVD videos are encoded a 720x480 resolution, with double the
frame rate of the lowres ones (29.97FPS up from 15FPS)
