Help, can't play burned cd on my ###ne

[CDRultima]

Could somebody help me with this problem? I have bought a sony ps-one, and want to backup some games. So first i tried to burn a psx-game (Croc2 and Donald Duck goes..) with cdr-win. I have been using cdrwin with the setting as shown on de psxcopyworld. The burning gives no errors or problems. But my pc cannot read or access the burned cd. My ps one with mod-chip inside shows only images af the memory card and cd player when i try to play the burned cd's. I am using kodak cd's. My burner is Philips Cdd 3610.
What i am doing wrong? Is my burner not capable of copying psx games? I am using the wrong cdr's

Could somebody please help me.

Greetings
