HR20-700 in OKC. Getting some channels and searching for signal 771 on others. Then they'll switch back and forth to the ones I got I don't get and vice versa. While other times I've been able to get all the channels. I have rebooted and refreshed on the website and it hasn't help. Calling CS today. Very happy though to get it up and going. Wish FSN was added witih OU game this weekend.
Have you checked the signal strengths on both tuners? Sounds like one of them is not getting it...
