In my case I would be replacing a GeForce FX 5200 with a vdpau PCI card
in a frontend only machine. Possibly this card based on the wiki?

Being a frontend only for watching recordings, there wouldn't be any
other capture devices going at the same time. I would want to watch HD
and analog recordings, all still MPEG2 based.

The HD recordings would be done by my backend machine using an HDHomeRun
as the source. So I assume they would be MPEG2. Analog would still be
done with my PVR150/250/350's.

That's if I understood you correctly.

Like you said, based on what I've read on VDPAU I can see why it's not
even a mention on sites like newegg.
