I just got ESPNU last week and can't believe how bad SD could be. I switched from the Absolute package just to get the RSNs and knew they would be a mixed bag and figured I could tolerate some SD by watching it on my smaller 32" LCD, but again the worst SD imaginable on Altitude and Fox Sports.
If Dish needs the bandwidth I'll be glad to give up about 190 of the other channels I don't watch.
