[mythtv-users] XvMC/Xv error and Renderbuffer error

I'm running a Via SP1300 with the openchrome XvMC libraries. This works 
quite well and far better than when I use 'Standard XvMC' in TV 
Playback. However 2 errors exist. One had shown up for some time the 
other is new.
I am running SVN 9403.

The first error is not fatal and I am not sure if it really is an error, 
or just a 'condition'. This error is the on complaining about Xv video 
childrend.
The second error is absolutely fatal: the 'renderbuffer' error aborts 
the frontend.

This 'renderbuffer' only manifests itself on a return from 
Utilities/Setup -> Setup -> Appearance in mythfrontend. Going into Setup 
is not apparent from the log. I was fiddling with bit-rates and other 
settings in an attempt to get rid of the other error when the second one 
was revealed. The second error is repeatable.

Log follows:
