I'm having similar issues.
I'm using the Power DVD 7 MPEG-2 decoder.
I have a FusionHDTV-DVB-T Hybrid card.
When I view TV using the Fusion software, all is well.
When I run TV within MCE it just says 'Stopped' ...then there is a resume button, but when I click that it just stops again
Sometimes I wish MCE would just burn in hell
