[mythtv-users] Semi-OT: Any unencrypted QAM on Comcast in south King County, WA?

[David Brodbeck]

So, I'm looking to replace my secondary tuner, which recently stopped  
recording sound.  I'm starting to ponder HDTV.  I'm too far out in  
the fringe to realistically expect OTA reception, and I'd hate to  
spend money on a tuner and find I had nothing to tune with it. So ...  
Is there anyone who has Comcast cable in southern King County, WA who  
can tell me if there are any unencrypted QAM channels on it?
