Hey guys, I've been having a hard time getting information on a V4 with model number SCPH-30000. I've heard that this version will play DVD-Rs, but it won't play DVD+Rs. Can anyone verify this? Also, if they can't play DVD+Rs, would they be able to play originally pressed dual layer DVDs? I don't know if this is a stupid question, but I don't know anything about these sorts of things. Finally, how compatible would they be with Swap Magic? Thanks in advance, guys.
