DVD rip - Game backup problem

[prb317]

I'm currently working on backupping all my ps2 games, and I see that my ps2 have problems on the DVD-games, so now I've decided that I can rip the music and/or videos of the dvd's, so they are able to fit on a cd-r. I don't know if it is difficult to do this, or if it's just a few games this works for, but I want to try.

Now, the first game I wanted to backup were WRC: evolved, I downloaded the ripping guide from this site, but enqountered a problem when looking for the music files. There were no large files, except a file called DVD.dat, at 3.40 GB, I'm wondering, does this mean that it's impossible to remove music and video, or can anyone tell me a good way to do this. I can't open the file anywhere, so would really appreciate some help here.
