>> I have a Hauppauge HVR-2250 PCIe x1 card. Dual ATSC/QAM tuners. The card has hardware NTSC encoders, but the Linux drivers do not support them. The digital side is supported with drivers built into the kernel from 2.6.32. Previous kernels require a driver compile, but it is pretty easy. I do not use FC12, but I think I have read that FC12 requires the driver be compiled. Search the list archives for details.

The HVR-1250 is NOT the single-tuner version of the 2250. The 2250 has hardware encoders for the analog side, the 1250 doesn't. The HVR-1800 is more akin to the single-tuner version of the 2250 than the 1250.
FWIW, my master backend runs Fedora 12, and has both a 1250 and 1800 in it, both of which Just Work (after dropping the required firmware files into /lib/firmware) without having to compile anything. They also Just Worked in the Fedora 11 days.

TV cards use several drivers for the various chips on them. The cx23885 driver is just one of them. The issue with the 2250 is that the pcie bridge driver for the card hasn't until very recently been in the upstream linux kernel.

Or get an HDHomeRun. And use multirec.

But that really has nothing at all to do with the choice of capture card, unless the driver is bonged in such a way that it only works with a really strong signal.
