I have a 622 that is being replaced (shipped out today) after having issues the last 3 weeks with the receiver locking up every night during updates. I actually witnessed it last night. A message popped up saying that channel info was being updated and the progress bar never moved. Screen went to static on TV2 and blank on TV1 and the receiver's fans kicked into full gear. I normally just find it in that state in the morning, continuously rebooting itself. Power button has no response, so a power cycle is needed before the unit will function. I'm pretty ticked because I will have to re-program all of my timers and pay the EHD activation fee to keep the shows that I have recorded and move them over to the new unit. Of course I'm leaving on vacation tomorrow so it's a crapshoot whether the timers that I have set for next week will actually get recorded. At least now I can check it remotely on dish.sling.com to see if it's still online... Is there any way to transfer timers from one receiver to another? That would be awesome.
