First off, all HD will be mpeg4 on August 1st, there will be no mpeg2 HD after that date. Dish mirrors all National HD on both 61.5 and 129 and is putting some dma's up on 61.5 as it is easier to get, other areas have no problem getting 129. You would need a Dish 500 for 110 and 119 and a wing dish for 61.5. You do not need a Dish 1000. If you do not subscribe to your locals, your OTA guide will not have any info. Your RSN is available on the programing package AT100+ or above, not on your local package.
