Problems with Getaway & Manhunt

[Prof_F]

Hey,

i'm having problems with backups of said games. The Getaway i created an image of using DVD Decrypter and then burned it with the same program on a traxdata 2x dvd+r. It would stutter a lot on the title screen and usually wouldn't start loading the game. I then found out this forum and bought a cakebox of Traxdata 4x dvd-r. I burned it again with almost the same results. So i remembered this forum and found out Recordnow Max was the program of choice for PS2-games so i made a backup using that program of my first burned backup (could this be a problem?) agina on a Traxdata 4x dvd-r. Now it still stutters on the title screen but loads ok.
With Manhunt, i had to make a copy using Nero at a friend's house. First on the dvd+r, which had problems with the sound during "executions", then on the dvd-r, whicht runs ALMOST perfect.
Do you think if i from the start had backupped the games using only RnM and dvd-r, things would be better now?

Damn, that's a bigger post than i intended...

Thanks in advance!

ps. i have a NEC 1300 and a V7 PS2 with the Ripper 2 deluxe
