Magiciso is your man here. I've been using it for a year now... the only thing you have to do is make sure you convert it to .bin and not .iso (hey, GP2PSX emulator anyone? You gotta use .bin anyway, remember?) and it will play on my emulator =p
That's just for ripping PSX games, you can burn with Nero/DVD Decrypter/Alcohol or whatever after that.
I think you can rip all you want in the trial version too...
