booting backup's problem

[matt1]

Can anyone help?

I have a PAL v4 neo4 ps2 and have made a backup copy of gt3. I used gta-vc as my high toc original but can't get the backup to work. I have followed the boot up instructions on this site to the letter but still I get a blank screen. I can hear the disc pulse spinning but no game. I use recordnow max as my burning software. I used laser brand dvd-r's as my media. Could this be the problem????? I have used this brand to make a copy of a movie & it works on my ps2. Are games different??????
