I was wondering the same thing - are PCI/USB ATSC tuners not eligible
for the coupons? (I'm in the UK, so don't know the US situation)

Not only do you lose OTA HDTV entirely (with its improved resolution,
video and audio quality), you also lose the higher quality video and
audio seen in digital SD transmissions because they are first
converted to analogue video, then re-encoded back to MPEG-2. A PCI/USB
ATSC tuner records the digital transport stream directly to disk with
no loss in quality, supports HDTV, and requires no further setting up
(LIRC for example).

I'd suggest getting a PCI/USB DVB/ATSC tuner when usable OTA signals
are available, and only resort to using a framegrabber/hardware
capture card when there is no other means of getting those signals
into the machine.
