A few days ago, my 625 stop downloading program guide info. I've a) done the check switch, b) powered down/hard reset, and 3) reset with the power button. Whenever I get the screen that asks if I want to download new guide info, I select yes, that screen remains for about 3 seconds and then goes away... no info downloaded. Two questions: seems to me in the past when I've done "check switch" it has gone through several tests. Now "check switch" does Test 1 of 1 test. Secondly, is there a particular sat/tr that dish uses for the program guide info? Where does it come from. I thought maybe I've lost a signal that would have that data. BTW: I can access already-recorded programs on the DVRs, but cannot access the timers. All other features of the 625 seem to be working fine. Any ideas? Thanks!
