not sure about your particular tv device, but i have a hauppauge pvr-500 and it appears most if not all of the hauppauge cards don't currently work under linux 64. i think either ivtv needs to add support for it or hauppauge needs to release 64-bit drivers or both for it to work. as for the pvr software for linux, i'm not sure if there's any that is 64-bit yet.
Hauppage never released drivers for Linux.
The PVR line of cards were top of the line in affordable TV capture cards with hardware encoders for a long time, so the people at ivtv.sourceforge.net reverse engineered the card enough to make drivers.
Their drivers work on 64bit Linux versions.. (and have been for a while) you have to compile them yourself probably though.
The only company that I know of that released open source drivers and documentation (I know for the drivers, I think for the documentation.) is Plextor for their "ConvertX PVR" (models PX-M402U and PX-TV402U). These are USB2 devices that encode in mpeg2 and mpeg4. I beleive that mpeg4 recording is supported by Mythtv at this time.

I expect that they would work in 64bit mode.
Since everything in Linux is open source, with a few notable exceptions (propriatory drivers for video cards and wifi devices, as well as immature drivers), we don't have the same problems that Windows has when using multiple archetectures. Almost all the archetectures that Linux supports, supports almost all the hardware that Linux supports.. pretty much.
