[mythtv-users] Tuning problems with HD5000

I am having problems with an HD5000 that used to work. I needed a  
kernel upgrade to fix some network instability, and I think that is  
when the problem began. I don't watch much DTV, so I'm not certain  
the problem started with the new kernel.

My symptom is that the card is recognized properly, but it doesn't  
seem to want to tune. Most of the time scan says it fails tuning, so  
of course azap can't get a lock. At one point, I don't know how, but  
the tuner tuned to the local PBS station. scan then thought it could  
tune, but it was always on the PBS station, spitting out a list of  
the PBS channels for each frequency it thought it was tuning to. When  
I would change channels in Myth, it would think it was on various  
channels, but always displayed one of the PBS channels.

Has anyone had this problem and found a fix, or is anyone having  
success with an HD5000 on a newer kernel (I'm at 2.6.22.1 on amd64)?  
I don't think this is a myth specific issue, but I'm hoping there are  
a few HD5000 users on this list.

Thanks.
