Hi, I just purchased a Bell ExpressVu HD receiver and now have two receivers in my home theater room. As there is only one remote code for an ExpressVu receiver, I will have to learn all the codes for a second remote address. This will mean a second remote as my original 15-1994 is tapped out for memory. Radio Shack now sells a 15-2116, what are the major differences between the 1994 and the 2116? Also I cannot find an "aspect ratio" advanced code for a Hitachi 51" widescreen TV. One final question, this TV has 5 inputs. To access each one you must bring up the input screen, arrow up or down to the appropriate one, then press right to get into the input sub-menu and finally press select. Does this procedure mean I can no longer use macros. Are there any discrete input codes? Finally, is the 2116 a better choice than the Chameleon 8? Thanks.
