The last few days when I turn on the receiver, it comes on at channel 101, (Dish home) regardless of what you were watching before. Mildly annoying, I don't like being told what to watch. Anybody else?
It is my understanding that this can happen if you mash the buttons on the remote or possibly if a remote button is stuck or pressed for a very long time (like when it is stuck in between couch cushions).
It happens for these reasons that I have seen myself or seen posts that figured it out;
It was left on an HD RSN
It was left on a channel not in the guide you are using
It was left on an OTA channel
It was left on a channel that changes transponders. (Something like the HD RSN situation)
And you won't like this one - possible early symptom of a hard drive failure or problem.
It can also happen as mentioned after a software update, I haven't had it happen after DISH downloaded programming as yet.
