[mythtv-users] Can't play recordings made pre- PVR-350 TV out

Instead of trying to display the video through the X driver, change
the MythTV settings to use the PVR-350 TV Out directly.  I don't
remember exactly which settings page it is in, but I think it's on one
of the TV Settings pages, or it might be in the General pages.  Once
you enable that, the output should be much smoother since you'll be
using the hardware decoder also.

Make sure you take your audio from the PVR-350 output and not from
your sound card, otherwise the video and audio will be out of sync
enough to be annoying.
