Well, since everyone else is chiming in on how great the HDHR is, I
thought I would offer my opinions on the HVR-2250.
Like the HDHR, it has an internal splitter, so you only hook up a
single coax cable to get your OTA channels. It works great and is
easy to set up as a DVB device. I haven't had any trouble with tuner
sensitivity, and it works better than the cableco supplied set top
box. Drivers have been in the mainline kernel tree since 2.6.32, I
think, with full analog (NTSC) support included since 2.6.37. You may
need to download some firmware to get everything working. The driver
was developed by Stephen Toth at kernelabs.org (
http://www.kernellabs.com/blog/?cat=3 ) The card will use a tuner as
digital OR analog, but you can setup 2 digital and 2 analog tuners and
use input groups to keep Myth from trying to access a single tuner as
both at the same time. You can even have one tuner recording digital
while the second records analog. If you only need digital, I would
not even bother to set up the analog tuners.
The HVR-2250 takes up a single PCIe 1x slot and is low profile if that
matters. I am using the card for ClearQAM. The only time I have ever
had bad recordings is when Comcast has moved the channels around, in
which case I just use Myth's channel scanner to find them again.
Basically, either HDHR or the 2250 is a solid choice for your OTA ATSC needs.
Now my choice coming up is whether to get an HDHR3 for cablecard
support, or hold out for a Ceton card to sit next to my 2250 to get
ClearQAM with multirec for broadcast TV while the Ceton picks up the
