I posted this in another thread but here it again, I found out during a couple quick power outages that the 722 can be set to receive SD only. My power went out and while my 722 was rebooting the power went out again. when it finished rebooting the 2nd time there were no HD channels available on any list.I went to my menu and pulled up my local OTA HD channels and somewhere along the line it said I would have to call dish to upgrade to HD. when I went to system info it said I had a 722 SD instead of 722 HD. I rebooted a 3rd time and it went back to normal, so I guess they have the ability to change a HD box to SD box at any time, in fact if needed then can probaly send it out as sd and upgrade to hd if a customer wants an upgrade. anybody else seen this?
