[mythtv] dlopen of xvmc library (please read if you use Via XvMC)

[Curtis Stanford]

I am experimenting with viaXvMC right now. I'm about to try the latest  
CVS support when I get home later. My earlier attempts met with  
failure: just a blue screen instead of video. If I ever get it working,  
I'd be happy to test something for you.
