Tom,
I have a Mitsubishi projection TV too. You can get the advanced codes for the TV and program the remote to select any input directly (no cycling through). For example, to select Input 1, you would use advanced code 199 (I think) and assign it to any key using the instructions in the Robman's manual at
www.hifi-remote.com. Without looking at this website, you only use about 30%-40% of what the RS 1994 can do.
