I had the same double channel problem with my Viewsat Extreme. You can get rid of them by trial and error. It involved going to both channels and pressing Guide in between or something like that. It was not fun. The only way I really solved it was by reflashing with a factory bin, loading new bin, and rescanning.
There are different versions of factory bins out there. The first one I tried for my Extreme made it go crazy. The display was flashing all sorts of garbage. I thought I had fried the receiver. Loading a different version fixed it. Hopefully your Pro does not have a variety of factory bins like the Extreme.
I solved it by selling my VS for $20.00. What a piece of junk. Using favorites was a chore, picture quality blew and it had trouble scanning all channels. I only bought it because of the support. What a mistake that was.
