Yes - doing a search after Mike's mail came up with that, I'm going to
roll back when I get home. I had tried OpenGL Vsync - but I'm definietly
using a newer driver than 7676, so that sounds like good advice. I now
know what I should be looking for in the logs from an earlier mail too,
so I'm feeling a lot more optimistic about sorting this out! The
ChromaKey stuff sounds like the way to go as I was just reading
something about that in Nvidia help! Maybe I'll have XvMC going without
any downsides : ) I have 0.18 from ATrpms - but I'll do a search on
ChromaKey OSD.
Thanks for the help!
