okay, can someone who knows what they are talking about tell me what the deal is on these sites? is the "grade a" dvd media going to work with ps2? are the unbranded princo discs any good, what are the best deals here? im not really new at this, but im sick of using apple media, because i used to have a WHOLE lot of it and now that i have used it all i need to know what is cheap and trustworthy.
thanks all!
matt.
