What had been a once in a while occurrence, I'm now having the same problem pretty much everyday with my VIP622 box. I normally watch the box in the morning before going to work and then probably won't turn it back on until at night before bed. I don't physically turn off the box, but let it go into sleep mode with no activity. Lately, when waking the box up at night, it will show the channel that it was last left on in the morning, but as soon as I change the channel, it will go through the Acquiring Signal process and it won't find a signal for that channel or any other channel. Rebooting the box is the only solution to my problem. Anyone else have this issue?
