I feel that we reached the time to begin to force SD out. People are constantly calling for 3D content, but HD isn't even perfected yet do to SD hogging up the room. I get that SD uses less space than HD. But why keep repeats there?
Then we have channels like ESPN who doesn't even use true SD anymore. They down convert the HD into a letterbox screen. So Disney won't let Dish have those channels in HD, because they want to charge Dish twice to simply have the true HD image, then have a second image that ESPN compressed for them.
Basically it's time to slowly force it out.
