You should give the search engine a whirl. More factors than just +/- format come into 'what works best' equations. Older version PS2 like - better, same as older standalone dvd players like - better. Now you'll find new PS2's and Players are compatible with either. I use TDK-R (TTG01) 4x and they work fine with my PS2 backups and DVD backups. I have used a few of the TDK+R (RICOHJPN) and found they work just as well. Good media can make all the difference.
Just a tip, that whole 'please reply' thing is unecessary.
