I think I may have found the problem. I had upgraded to the latest factory firmware. I think that maybe it didn't take properly.
I went back and did a system reset to default settings, re-installed the upgraded fw, and did another default reset, and now it seems to be moving and locking on to the sats correctly.
Since then, I've been using the standard TP scan from within the sat setup menus for now on the regular FTA birds. I'll try the blind scan on a couple of AMC sats, once I get the G's and IA's done. BTW, the standard TP scan is very very very fast. PQ is excellent, as well.
