I'm trying to play this with my Epiphone aj220 sce and can't calibrate the thing. Can anybody help me out please?
Do you have all of the equipment necessary to play? Anyhow have you figured out the problem? Its been 4 days.
There are two different calibrations in RS 2014.

In the video section of the options menu there's a setting called "display lag correction" or something. You can reach the setting while paused in a song iirc, so i'd recommend getting into one and setting it manually until you get it set how you want.

The other is a button prompty at the bottom right of the screen when tuning before a song. I believe it just calibrates the volume correctly.
