Please don't take anything I write about QAM as authoritative.  I 
currently only use OTA (and satellite for standard def), but I 
experimented with QAM last month with Time Warner.  It appears that the 
only QAM channels Time Warner Summerville, SC sends unencrypted is ABC, 
FOX and some shopping channels.  CBS, NBC, PBS and CW were not available 
(or at least I couldn't find them).

I have many different ATSC cards HD-2000, HD-3000, Air2PC 2ndgen, Fusion 
HDTV5 PCI and USB, and HD Homerun (dual tuner 
http://9thtee.com/hdhomerun.htm ).  I only tested the Fusion HDTV5's and 
the HDHR with QAM as that was all I had in my system at the time.  My 
QAM256 signal strength was about 90% IIRC.  The HDHR was the only one I 
could get to work in the limited amount of time I had to test QAM.  
Running firmware from Aug (not latest now), don't recall exact version.  
The Fusion HDTV5 both PCI and USB wouldn't pick up anything in the 
scan.  The HDHR found a lot of stuff, almost all of it was encrypted.  
Anyway, like I said, I am back to OTA only right now using the HDTV5 USB 
and HDHR.

Don't take this to mean only the HDHR will work.  I have not tried the 
latest pchdtv card (HD-5500)or the 3rd gen Air2PC card (HD-5000).
