I know this has been out in R1 for ages now but its just been released in Australia and its the only disc of its sort available here. So, i would like to know if its worth money? The sound of it is good, but does it actually work. I'm keen to see all the demos on it, music,visual,dts demos etc. But would like to know how the calibration tools are. I know discs like Avia are meant to much more indepth but it would cost a fortune to import. Any info would be great..cheers!
