Open GL settings in MythTV

[lmwashere]

I would like to enable OpenGL vertical sync to improve my picture quality. Everytime I exit Myth the setting resets itself. Is there a way to make this setting permanent?

I read this post, but I am afraid this fix is a touch over my head.

Was there ever a walkthrough posted anywhere?

Thanks
