I can't help with your video freeze issue, but are you sure this isn't a 
typo?  You say your playing back 720p and 1080i on a 1Ghz Pentium-M with 
with Nvidia 7300?

I'm not sure, but I think the myth-vid bits are now in Svn - I thought 
there wasn't an improvement in performance with the OpenGL rendering? 
If there is, I am pleasantly surprised.
