Thanks for the input. The DW and I are old school we do not have satellite HD at home and get our local channels from an over the air TV.
Our home satellite dish is the smaller version, it has only two horns, one for the upstairs and one for the downstairs receiver. We never upgraded to the larger three horn HD dish.
I seems like the easiest method for us would be to take the downstairs receiver and use it with a cube. That assumes our receiver is compatible.
Given the quality of the 17" flat screen Jensen HD TV that can with the TT, I am not to worried about picture quality :) :) but I do like to get the evening news.
