"insert disc" error when using cd-r on messiah

[thanku]

Hi again

I tried as u said, I burned a game with 4x speed, the game started fine at the first try. But when I tried to start it again I got that insert disc crap again... I also ran out of Verbatims so I bought Imation 80-minutes cd's which I burned that game on...

btw, I've heard that if a cd-r has a dark-blue surface it means that the cd-r is of the finest quality, but if it has more green/yellow colored surface it means that the cd-r is of bad quality. Both Vebatim Datalife and Imation has green/yellow surface... Is this just crap and somebody has tricked me???

thanku
