For Playstation "backups", Cyanine-based CD-R's work better than Phthalocyanine-based discs. These discs are compatible all-round and the best ones are made by RiTEK and Taiyo Yuden. Phthalocyanine-based RiTEK, Prodisc, Ricoh, and Mitsui-made discs are outstanding for audio, video, and data. Azo and Metal Stabilized Cyanine-based discs (Mitsubishi/Verbatim, old TDK) are suitable and give high quality results if and ONLY if your drive is compatible with them (i.e. LiteOn and LG drives HATE them!).
You should stay right away from ALL discs made by CMC Magnetics, Lead Data, Digital Storage Technology (DST), Grand Advance Technology (GAT), Princo, King Pro, and Sony Cyanine (Made by Lead Data using Sony's ATIP, the Phthalocyanine ones are alright).
@cd pirate: There are many phthalocyanine-based CD-R's out there that are extremely reliable. Examples include Ricoh(Made by RiTEK using the Ricoh ATIP code), Kodak Gold Ultima or Ultima Silver+Gold (Used in older <24X-speed drives), Mitsui, newer Prodisc, and newer RiTEK branded as TDK.
