I recently picked up a Dual 533 G4 tower (see sig). The Pioneer DVR-107 installed without difficulty, it burns CD-Rs without a problem and plays DVDs just fine. I'm planning on upgrading the processor with a single 1.2 G4 (or better) when funds permit. However, I bought iLife 2004 the other day. It says on the box it requires a 733 MHz or faster G4 in order to use iDVD. I've seen how well a Dual 533 performs against even a 933 a la Barefeats, so I figured I'd try it anyway. But when I try to burn a project to DVD, the little flashing "burn" icon flashes for a few seconds, then speeds up, then stops. Alternately, if I choose burn from the file menu, I get beachballed for 10 seconds or so, then iDVD quits. No burn. Is there something stupid I'm missing here, or is my system really too slow? It doesn't seem slow to me. Maybe a media issue? I'm using Memorex DVD-R 8x media. What's up guys?
