I have a quick question. I am looking to purchase a new remote for my "Theater" system. All the equipment, TV, Receiver, Blue Ray, CD and cassette, are Sony. the ages vary from brand new to several years old. Will a URC remote, something like the MX-880, MX-3000, be capable of replacing the Sony remotes completely? As everyone here knows there are a lot of functions on these remotes like accessing setup menus, and will the higher end remotes also be able to access these functions?
