VIA XvMC does not support most MPEG-2 streams. It only decodes
a subset of valid MPEG-2 streams. The PVR-250 recorder can be
configured to only generate streams that VIA XvMC can support,
but the Nova-T can not.

There is a long standing effort by the OpenChrome developers to
extend the VIA driver to support standard XvMC acceleration. If
you can program, it would be a good idea to join their mailing
list and help them get it done.

The thing to try first is to install MythTV and OpenChrome from
the development versions to see if this is something that has
already been fixed.
