Just a few quick questions on Directv. Is there any special features I should look for when buying a box? Do they have boxes that support DD5.1? If so, will everything be broadcast in 5.1 or just a few special movies (like say HDTV). Is there anything I should look for when buying a system....any special brand or features that stand out over others? Finally, where is the best deal on a complete system? It seems like I've always seen them really cheap, but now that I'm looking, its like a minimum of $150 for the dish and reciever. Are there any better deals than this? Point me in the right direction if you don't mind. Thanks guys.
