so it was the 22k switch then...hmmmm.....
Well, at least it's the software that talks to it! The Pansat unit working properly tells me the 22khz switch itself works fine. Somewhere there's a problem in how the Visionsat talks to the switch. In any case, your advice has helped tremendously! Can't wait to scan-in more, add a V-box, and make it automatic. The recording feature seems to work great thus far, too! May be "old" by today's standards, but a very nice receiver.
