Suddenly they're adding all these HDTV channels...I understand that the VOOM channels are off the VOOM/Rainbow dish, but what about the others: HGTV-HD, FoodNet-HD, ESPN2-HD, locals in HD, etc. etc. I thought they were stretched already. I know these are in MPEG4, but HDTV MPEG4 still requires more bandwidth than an SD channel. I thought D* was better set for HDTV with the launch of Spaceway 1 & 2, but DishNetwork is taking all the press by storm lately...so, where are they getting the bandwidth??
