Hauppauge now claims that the MVP can play mpeg-4. As far as I can  
tell this is by transcoding the mpeg-4 file to mpeg-2 on the fly with  
software and then sending the result to the MVP, because the MVP  
hardware has not changed.

Unfortunately this is proprietary Windows-only software that does the  
transcoding, so we're unlikely to see it in Myth anytime soon, it  
would have to be developed from scratch and I doubt there would be  
sufficient interest to warrant the development effort involved.

It should be possible in principle though.

OTOH I don't see why you couldn't create a user job to transcode a  
file to mpeg-2.

But the cost of a PVR is about the cost of one hour of labor on such  
a project, and is thus probably the better solution.
