I take it that Rob hasn't done this... he just doesn't know what he is missing. Excuse him will ya....
I havn't tried it with my SACD copy and I think it would be great. I need to find a copy of Wizard of Oz to try it out with. One thing I did do though was I downloaded something called "Dark Side of the Rainbow." Someone was kind enough to rip Oz, rip DSOTM, and splice them together for one nice short movie.
