Does the PS2 read DVDRWs?

[Jmanultra]

I guess this is a stupid question but my buddy backed up a couple of his games on DVD+R discs. I have a version 4 PS2 with a Magic 3 chip installed and I've been told that I should use DVD-R discs for my system. His DVD+R backups booted in my system so I was considering getting a couple discs so he could back some titles up for me. I was thinking that it would be worth the extra $$$ to get DVD+RW discs in case the copy he makes doesn't work in my PS2. That way I could just erase the disc and try again. Do +RW discs boot just as easily as +R discs?
