The current MythTV CVS with XvMC VLD decoding crashes when changing
a channel.
This is due to to the test to see if a valid XvMC port is available
in the static function VideoOutputXv::GetBestSupportedCodec() on lines
820->838. This fails on a channel change as the latest XvMC code
does not close down the XvMC port and so no ports are available for the
I'm not sure where is functionality should be put
(VideoOutputXv::InitXvMc() ?) so I have put a "#ifdef" around this
A patch to fix this is enclosed, but as stated, the code really
needs a better change.

I think I may nearly be there with XvMC VLD decoding ...
