Need some help with PS2 DVD backups

[dippy1423]

I have a no solder mod chip and Action Replay 2. I have successfully backed up CD based games but recently purchased a DVD burner and have had no luck getting any of the backups I make to boot.

My first question is, does DVD+R work. I have an HP DVD200e DVD+R writer. I have backed up the games using both NERO v6 and a program called Alcohol 120%. I have attempted to back up NCAA 2004 and Madden 2004. I have attempted to use the boot up method for the no solder chip using FFX as the boot disc.

I have used Maxell and xhypermedia discs with no success. Anyone that could give me some advice would be appreciated.
