Those XIDs were from the 9400 log.
The 8500 nvidia-bug-report doesn't show any XIDs.
Unfortunately, the 8500 Myth log doesn't include any VDPAU debugging information. Can you please set the following environment variable in the MythTV frontend (most likely, run the following command in the shell you use to launch MythTV):
and verify that the log shows some form of VDPAU error message and backtrace when the pre-emption occurs. This information may show where the problem is occurring.
