This is the neatest toy...I just managed to replace 4 remotes with this unit, maybe 5 if it accepts my N6 processor. One thing I noticed that if you have a mutiple DVD disc tray you cant select ecah individual tray to play that particular DVD/CD. I am still experimenting. I manged to program my tv,dvd,cd,PS2,Xbox,DLP,satelitte through this easily. On the projector (X2 and 4805)I noticed that there were only 2 selections for screen size and I have 4 on my unit itself, I havent gone through all the menus thoroughly though to see if they are there.( I paid $110 for mine off a member here..thanks)
