"I have the Yamaha RX-V1400. By far my biggest complaint is the "multi-channel" input is a toggle selection, not discrete. This means it is impossible to automate switching to SACD/DVD-A via a remote control macro"

joe, i have the rxv1300, and on the remote, way up on the right hand corner is the 6 channel button. is this what you're looking for, or am i confused. i can toggle between the two modes with this button.
