John replied off list:

"http://linux-media.vger.kernel.narkive.com/kAviSkda/chipset-change-for-cx88-board-pinnacle-pctv-hd-800i

Wonder if any code was ever integrated?"

It looks like basics of a patch was developed to support the card but
it was incompatible with the existing cards and nobody took the time
to understand how to differentiate between the older 800i and the
newer 800i. So, the problem fell on the floor.

I'll look through my card library. If I have an old _AND_ new rev then
I'll find an hour and see if I can find an acceptable solution.

Summary: PCTV released a new 800i (quite a while ago) changing the
demodulator, which is why the existing driver doesn't work.
