Your cable company's DVR only has one video output, and barring some
excessively complex setup where the computer schedules recordings on the
DVR, and slowly pulls them off in real time over the component output,
it will function no different than a dumb cable box. You would actually
be better off swapping the DVR for a dumb cable box. It will be
cheaper, and will have firewire, which if nothing else will be more
reliable than IR for remote control.

The HDHomeRun Prime has been usable in MythTV since before the 0.24
release. Several of their employees use MythTV, and they have been
testing the HDHR with it in the Bay Area for months. It should be
usable as soon as Cable Labs certifies them.
> So, basically, it looks like the hardest thing will be to get a cablecard tuner hooked up to make use of both (or all three) tuners. I signed up on a mailing list at Silicondust's website so I will get notification when the new product is available.
You will be limited to those channels that are marked 'copy freely',
which will be the same channels you would otherwise be capable of
pulling off a cable box over firewire. Effectively, you're trading
$20-30/mo in box rentals for a $4/mo cablecard rental and a $250 tuner box.

That depends. The AIW cards were never well supported in Linux, and the
older versions were not even capable of capture. The software would
define a box on screen, and the graphics card would copy the video
frames straight into it. It was for video playback only.
