My 722 rf output that feeds another tv used to be combined somehow so that OTA would also go with it. Ch 60 got me dish channels while OTA would be available by tuning that tv to those channels also. One day about a month or more ago, this stopped working, ch 60 was very fuzzy. Suspecting my OTA 1 to 4 amp went bad, I removed the OTA option and recently bought another amp. It made no difference and now I'm stuck. I've tried various splitters, combiners, etc, but OTA is no longer available and ch 60 is very fuzzy unless I feed it directly to the other tv. 1. Did dish make the 722 like the 622 where only dish channels can be sent to tv2? 2. If not, why can't I see both anymore?
