I have a Dish 6000 receiver with the OTA cartridge. I have a Mits 65819 which will not accept 720p. My local ABC station is going to begin an HD(720p) broadcast soon. I have been told that my Dish 6000 receiver will upconvert a 720p signal to 1080i. My questions are: -How does it look? -How is the picture different after it is upconverted? -How much different? -Is there enough difference to find another solution to get HD? -Which antenna would you guys recommend to use with the Dish 6000? -Is it as simple as connecting the antenna and its ready to go? -Anything else I need to know? Your help is appreciated.
