Ok.. here's a new one for me! I have a ViP622, and I subscribe to Dish locals for my area and I have my OTA antenna connected. Tonight around 12:45am or so I noticed several Dish locals (satellite locals) had "off-air" listed in the EPG and those channels are indeed off-air from satellite. BUT... the OTA channels are not off-air (verified by a non-Dish digital receiver I have in another room)... yet, the same Dish locals that are off-air also will not tune OTA. For instance... Channel 22 via Dish says "off-air" and is unavailable.. and my 22-1 digital OTA channel says "no signal" as well. However, Channell 11 via Dish is not off-air and I can tune to my 11-1 digital OTA channel. I have never seen this behavior before... where Dish is taking their satellite-provided locals off-air for a time (looks like about an hour according to the EPG) and causing the receiver to disable the OTA tuner for the corresponding OTA channels as well. There is no reason to do this, so I have to think it is a glitch. Anyone else seeing this or has seen this before?
