wow, jump down my throat. I didn't mean to offend you, I was just stating
the differences in what I was seeing and what I read on the wiki.  Maybe I
should have used my backspace key instead of correcting myself inline.  I
realize they are not the same problem (as I'm not using xvmc), but just
similar symptoms.  Again, I was just reporting what I was seeing in case
anyone out there was also having this problem, because I couldn't find any
info on it anywhere except that one statement, which as we have determined
is not the same exact problem.

Just found this as well.
http://svn.mythtv.org/trac/ticket/5999
Although I'm not sure if its exactly the same problem either.  He can't get
xv-blit to work, but i'm only seeing the problem with gl.
