I have a Dish 500 system, with the 4900 rec. If I get the 811, is there anything special I have to do to install it myself other than simply swapping boxes?
You'll need to hook up a decent antenna for the OTA HD and digital stations. Otherwise, it should work fine. It'll download new software the first time you power up. You'll probably want to run a check switch as well.

Thanks for the info, everyone. One more question: With my Dish 500 and the 811, will I be able to get all the Dish HD signals? I read here I might not get CBS-HD. Is this true? And if so...why???
Depending on where you live you may or may not qualify to receive CBS-HD.
If you live in an area that does not receive OTA broadcasts and subscribe to distant networks you can receive CBS-HD.
Or if you live in one of the DMAs in which CBS owns and operates the local CBS affiliate AND you are not in range to receive the broadcast of a CBS station from a neighboring market you can receive CBS-HD.
