This couldn't be right? I've successfully set up the 50 favorite channels, but when I'm using them I want to adjust the volume or go up or down with the channel. Why doesn't this work? I have to go to my SAT setting to adjust the volume/channels. How do you make these buttons work while in FAV mode?

Did you go TO the Fav page *FROM* the SAT device page? If so,then your remote should control vol and channel in the same way it does when you use the SAT controls. It works fine for me.
FAV is not a device; your vol. and channel buttons will control whichever device you were using before you jumped to a fav page. If your "ON" button macro jumps to FAV page, then make sure you tune to a SAT station in the macro *before* you jump to FAV.

Also you may want to use the "punch through" for your volume settings to carry them through to all the appropriate devices.
Good luck!
