I recently got an HR-20, with the new dish installed...major issues, too much to list. My questions deals with after customer service "issues" are resolved. I have had a standard definition Tivo for over 4 years and a feature of this unit that I love, was being able to toggle between channels, to where you always have time to fast-forward through the commercials. In the ~3 hours that my HR-20 was working, I was unable to find out how to do this...Is this possible, or am I S.O.L., just like my customer satisfaction???
