Have I done this right?? Newbie

[diannemm]

Hi to all,
I have just tried to make a backup of 'Enter the Matrix'.
I have a pioneer dvd AO6, and I used Nero 6. I just copied the whole disk to my hard-drive and then burnt it (as is)onto a Verbatim dvd-r using 2 speed. I have a magic 3 chip. When I put the back-up in the ps2 it would not boot, just keeps saying 'reading disk'. I have never tried to do my own backups, but I have others that do work. Do I have to add anything extra to the image file. Have I done everything right. I really have no idea, any suggestions would be appreciated, it did say it burnt successfully, it just seemed too easy? Have I missed something.
Thanks.
