Hi list.

I'm working on a piece that's most likely going to be shown on a Macs running OS X and I'm running into a strange issue with GEM. The piece involves a short video clip that moves back and forth amongst the frames. As long as it's moving between frames, everything is fine. But as soon as it stops somewhere, it starts alternating between the correct colors and their opposites causing it to flash. This doesn't happen on linux, only on OS X. Anyone know why this is happening and how I can fix it? I've tried a variety of video formats but nothing seems to make a difference. Also, when it flashes to the opposite colors, it looks like the resolution changes. Weird.

I would greatly appreciate any and all tips and suggestions.
