Dvd?

I'm just getting the hang of my dvd-rw, a m8 of mine asked me to do him a ps2 game which was a bin and cue file, I wrote the game to a dvd+r which I'm now finding out is no good for ps2 games they need to be burned on dvd-r or have I picked that up wrong? anyway I don't have any dvd-r discs and I'm trying to encode some avi to dvd 2night and with editing some camcorder stuff aswell I'm running out of space on my HD (I know I should get 1) I was just wondering if I can delete this 4 gig game off my pc and use this dvd+r I've already burned by saving it as an image or copy and pasting back to my hd and burning back to dvd-r tommorow when I get some discs or will the format feck it up?

Any :helpsmile: 2night would be nice so I can leave this vid encoding without waking up to no disc space :D
