I have pre-ordered the Gefen TV Scaler Pro. From looking at Gefen's other scalers all of them use a toggle button to go through the input selection (just like Sony does on their TV's). Does anybody have the discrete codes for any of the Gefen scalers? Any ideas on how I can get these discrete codes? I am currently using a Sony RM-AV300 remote. A little bit of a pain to program, but an excellent remote due to the ability to place a macro on any key.
