Over the past couple of weeks I have noticed that it will record ok, but some of the recordings are unwatchable (lots of pixelization, almost 0 sized recordings). Needless to say this is causing the WAF to plummet! Last night I ran the HDHR GUI to see what the signal strengths are, and it saw the tuners, but didn't find any channels. I can ping it, but nothing else seems to work. When I tried to record something with it, the tuner lights didn't even come on so I think it's dead.

Have you tried the obvious?  That is, is the cable and antenna in good 
shape?  I was suffering a similar fate.  WFA going down fast as about 
20% of the listed programs appeared not to exist on the HDD.  I have 4 
tuners in two different back ends separated by 10s of feet all connected 
to the same OTA antenna.  My problem?  I was cleaning and had moved one 
of the back ends.  That pulled the coax apart (never make your own coax :o).

I understand something similar happened at CERN's neutrino facility 
(they shouldn't make their own coax either ;) !).

-good luck
