Perhaps the black area of the video is not being noticed by my emulator anymore, as it usually crops this off and stretches the image to full screen size.. I guess it sees the black border as part of the mpeg, and refuses to crop it.?
Here are stills of the intro anim.
The first one with the big border is the latest mp2 X2 build. The one below that is the older 0.98 build.
I notice with the older build, there is more contrast in the image, and it seems bigger and centred?
It's not a huge deal, it just seems odd that there is a huge border. Perhaps it is simply a limitation of Riva?
