Re: XvMV freezes my MythTV-system
Are you stating that this also reproduces with a CRT when doing 1920x1080?
If you wish to use a display device other than a CRT, then you should be adding the UseDisplayDevice option, not the ConnectedMonitor option. See the driver README for more information on the correct usage of these options.
Please point me to content which reliably reproduces the problem.
