I found this link http://forum.rpc1.org/viewtopic.php?t=23370 Apparently, it is an easter egg inside iDVD that allows it to burn on an external drive which I think has been discussed before, here. However, it says that it will not work on a proccessor slower that 733mhz (or rather iDVD won't) and I was just wondering how people had got on adding mce superdrives, to a stock cube, when using iDVD. Also when I unstuff the doc it only has 2 very small files in it. Anyone had any 'luck' (oh Christ - here we go again :-) using this easter egg? Cheers Rossi
