i currently have comcast hdtv in michigan (detroit area). i really am not happy with the sd channels, but i have read that they are not much better with dishnetwork. i guess that dish is all digital so the sd channels should be a little better than cable sd channels, right? also when im watching a hd channel that isnt broadcasting a widescreen high def program , i get the bars on the left and right and cant stretch these channels. i understand with dish and the 811 reciever you can change the aspect ratio for the hd channels when they arent broadcasting a hd widescreen program. last thing, does direct tv offer any type of deals like dish for new customers. i call direct tv and they tell me that i have to contact a local dealer, like circuit city. when i talk to them, they tell me i have to buy a hd reciever. am i missing some type of promotion for direct tv. the last problem i have is that i was a dish customer 3 years ago, and local dish dealers tell me that i cant get the new promotions. when i call dish they say im eligible for a returning customer promotion , which seems to me to be the same as a new customer promotion......if someone can fill me in, i would appreciate it, im confused.
