Copying PSX With CDR-Win

[Kilbrain]

I am having great problems using CDR-Win and my Samsung Combo SM-304B. I have tried to copy both Sim###ns Wrestling and Gran Turismo 2 (I have a PAL Playstation) using them and Sony CD-Rs. There seems to be no problems while reading and burning. But when I come to put the burnt CDs in the playstation, hardly anything occurs. With Gran Turismo 2, the white sony logo just came up when i turned it on, and just went to the Memory Card/Music CD screen, however, by the sound of the CD-R in the playstation, I could hear that it had not stopped reading it.
With sim###ns wrestling, the sony screen came up, then went to the other playstation logo with the black background so I thought it was working, but then it just went to a blank screen but again i could hear that it was still trying to read the CD-R. What am I doing wrong?
