Screenshot showing the video in the corner. It should be fullscreen.

Ultima IX has MPEG-1 based video playback that is now working thanks to
https://bugs.winehq.org/show_bug.cgi?id=9127 being fixed. Thanks for everyone
who helped out there!

However, now the video playback only appears in the upper-left corner of the
screen. It isn't clipped, but it looks like the system is failing to change
screen resolution. These videos playback fullscreen on Windows. See attached
for a visual.
