I'm still using my circa 1998 Sharp 27" CRT TV, so HD is irrelevant.  I may
one day switch to something like the Ceton InfiniTV 6, but inertia and
other projects (like my never ending attempts at migration from Ubuntu
10.04 based MythTV 0.23.20100314-1 !!!) make this a low priority.

My set up is four DTAs controlled by hardwired optoisolator links plugged
into the rear IR extender ports (in lieu of IR LEDs taped to the DTA faces
with attendant cross-talk issues) from an IguanaWorks USB iguanaIR
transceiver feeding two Channel 3 & 4 signal combiners which in turn feed
into a pair of Hauppauge PVR-500 PCI capture cards.  No firewire involved,
just USB and video signals.  Yeah, I'm paying Comcast $16 per month for the
DTAs, but it hasn't been painful enough to justify buying a $280 "fix".
Besides, I suspect that I'd have a _big_ problem getting anything like the
Ceton to work with my current Ubuntu 10.04 / MythTV 0.23 system.  Even with
my current capability to record four shows concurrently, I occasionally
have recordings that get postponed to later due to overloaded programming,
so two or three stream (channel?) devices would have to be bought in
multiples, upping the capital outlay.  So I endure. ;-)
