PSX backups/ PS-X-CHANGE confusion

[copeland007]

the games so far are Lunar:Silver Star Story Complete & Vagrant Story. The originals still work just fine. I used CDClone to burn them onto Sony CD-R discs at x2 speed. i made the backups with Iso Producer. i'm wonderin if I should use a different cd format, I heard somewhere that might effect it. Like i said it works great in my PSX emulators. I load it up in my PS and the disc spins and everythin, but the screen just stays on the please insert import game and press start. at first I thought it my be my playstation, it was an old one, so tried it with my others and still the same thing happens. I have 3 regular PS's and a PSOne. Tried em all. thanks in advance.
