MP3 rippers tend to be really easy to use... just start 'em up, pop the CD into the drive... select the track you want to rip and hit 'o.k.'At least the good ones work that easily these days....
As far as the rest of the formats go, I have no idea what an "Oz's program" is... and MIDI's tend to bug the heck out of me...
Open G tuning eh?? I'm gonna have to give that a try... anybody got a good open G chord chart?
