I just installed MP RC4. This is the first release I've been able to get to work with QAM on my Pinnacle 800i tuner. The channel scan came up with a couple hundred of QAM channels. It tells me that it isn't able to view scrambled channels when I try to tune them. Is there a way to automatically remove the scrambled channels, or do I have to manually look at each one to see if it is scrambled?
