Does DVD+R media work on a modded PS2 ?
 

I am about to purchase a DVD burner and I was wondering, since all I see is DVD-R in relation to PS2 backups, does the PS2 accept DVD+R media?

Or doesn't it matter at all? Enlighten me :p

Yes, ps2 will play +r depending on your ps2 version.
v1-v3=forget it
v4=sometimes
v5-v8=yep
