[mythtv-users] XvMC Playback Segfault

I am getting a segfault when trying to use the following XvMC options with
an nVidia card and Watching TV/Recordings


>= 1280 720 



Video Renderer 


OSD Renderer 


OSD Fade 



one field 

At first I thought  the issue was due to opengl-sync being on in the compile
options so I turned that off, found someone else had a similar issue. It is
not checked in the playback settings.

Anyone know of a fix?
