Which CD's should I use burning ps2 games??

[MrNiceguy]

I tried it on Platinum cd's (80 min) but they do not seem to work, I burned them @ 2x and 4x......after that I tried one on a Plextor rewritable (74 min)speed, that one worked!! What kind of cd's do u people suggest?? Or isn't it just the brand but the 74/80 min??
