Non-Readable burns...

[Sven]

I burned a DC game with CDRWIN today, and the burning seemed
to work well. But when I wanted to look at the CD in the computer,
the computer just got stuck, same thing happened in the DC.
What did I do wrong?
Did I burn with to fast speed (4x) or use a too crappy cd (traxdata?

Thanks
