Good morning,
I have the same equipment as you, and so far so good.
Your ps2, is the last version and support all DVD formats ( DVD-R/RW and DVD+R/RW ). I making my backup by two ways, first using DVDXCOPY, the second I fowling the guides in
www.doom9.org
In Portugal, doesn’t exist very kind of medias, I try only Princo and I’m 100% satisfied.
Before starting the backups, make sure that you already have the last FIRMWARE of your SONY DRU, the version 1.0F.
Good luck man!
