You may have to ask a friend or someone, most "Help you" A/V services out there are just for set-up/hooking-up & calibration, Not teaching you how to work your remote, because there are soooo many diffrent set-ups out there people can have.
Forget about what each of the buttons do, my 2 yamaha receivers remotes both probly have about 75 buttons each, but I only use 10, so find the few ones you NEED, Power, Input (BD, Sat/Cable, Ipod, Tuner ect....), Volume & Menu.
Just Slow Down, open up the manuals & you having most of the stuff being the same brands will helps you out a lot, too.
