I have a V7 PS2 and a Swap Magic 3.3 and i have some problems with DVD+RW... I have my SM 3.3 since two weeks and before burning my backups on DVD-R I trying them on DVD+RW. Some times I had to retry booting it 2 times before it works but i had no problem beside that. But since yesterday I'm unable to boot my DVD+RW backups... I tried like 3 backups (+RW) but they don't work at all ... Each time the DVD speeding but it saying Not a valid PS2 disk after 15 seconds. But when I boot a DVD-R backup I have no problems.
