I must disagree with the possible interference theory. I believe it's a glitch in the receivers. I watch the channels that are offered in my local channel DTV package on the sat. or with my antenna with no blinking. Only channels not offered through DTV blink while off air. I've bypassed the HR20 and hooked my off air directly to the TV and no blinking. The channels in question are 10 miles closer than the DTV local channels. The hassle with this set up is changing video inputs from SAT to Off air on my TV.
My equipment includes:
All new RG6
CM 3679 antenna
CM 7777 Preamp
CM 9521A Rotator
Terk BSM-58 Multiswitch
Diplexers at each TV
Sony 60" SXRD (Which is the most awsome picture if I must say so myself!)
Onkyo 703 with 7.1 set up
It never fails, this puppy blinks right when there's something happening you want to see/hear! (What happend/what'd he say?)
It's a great feature the HR20 has to watch off air through it but I'm still searching for a fix.
