mythtv hd-3000 and QAM on cox question

[Mike]

Is anybody here picking up QAM broadcasts of local HDTV stations on cox 
analog service? Last week my mythtv stopped receiving anything on my 
HD-3000 card and it has since never come back. I've run some scans and 
am now seeing things showing up on a completely different frequency.... 
None of these streams look like they are video/audio anymore.

Is anybody else doing something like this and are you still receiving 
channels? 8VSB seems to be working so I don't think the card is broken. 
Seems like they just stopped sending the signal.

I'd also be interested if anybody has a HDTV with integrated QAM tuner 
receiving channels on basic analog service.
