Many hard to find discrete codes. I use the mute and prev ch buttons to toggle between my receiver and DVD/TiVo. I also use push and hold macros extensively. My two DSS receivers are next to each other so I have one set for ID 1 and the other to ID 51. I am still looking for a VIDEO 7 discrete for the TV and any Yamaha DSP discretes. Thanks to Greg for doing the hex conversions!
