Re: VDPAU Error: DISPLAY PRE-EMPTED
Does the display recover after that? I believe the driver can indicate that the display was preempted for pretty much any reason whenever it wants, and the application is supposed to recreate the VDPAU objects. If MythTV simply reports it as an error and exits, then it needs to be fixed.
That said, are the display preemptions accompanied by NVRM Xid messages in the syslog?
