Question on Burning Backups

[mdk2]

I have a Lite-on 40x12x48 CD Burner and I tried to burn copies of Tekken 4 and Tekken Tag but they don't seem to work. I'm using CD-RW discs and CDRWin version 5.0.2. My Jap Playstation 2 version SPCH 1500 doesn't seem to read the CDs. What seems to be the problem here? I totaly clueless here.
