For some reason one of my 722's is no longer showing either channel 501 or Channel 1 but the other one is. I tried doing check switch and forcing a guide update but that did work have a mixed arc set up 110,119,61.5 and 72.7 signal strength is good any ideas?

How is the signal strength off 61.5 transponder 21? Also is this a replacement receiver?

I sent you a PM on this

The 722/k will download VOD on a different schedule than they do the nightly updates. It's usually in the mid-morning (8-11am area) and the receiver will skip it if it's in use at that time. Sometimes it can take days for the receiver to update its list of available VODs if you are using it during that window.
