PS2 Media types for V7 and V9/10

[Cyber Akuma]

I heard that not all versions of PS2 can read all types of media, while I know the quality of the blank media matters as well, but can the V7 and/or the V9/10 PS2s read DVD-R, CD-R, and DVD+R media? What about RW? I know most can read CD-R and DVD-R but I heard some cant read DVD+R.

I think it was the v4 and earlier that has problems with +r.

Early Early modchips didnt support DVD 9 , + media, but As chips progressed
they made it possible even for the old Ps2's to play all formats. But the best media to allways use is - because this is the type that sony originaly used designed the ps2 to play, My type philips, byfar my opinion the best, memorex 2nd,
