is the game too big?

[suupasaiyajin]

Hey guys, I'm trying to back up some of my games and when burning is almost done it says there was an error. I look around and it says file size 4.8GB, is this bigger than the ritek-R are? Is there a way I can cut a tiny part or shrink something just a little bit? And can the PS 2 read -RW's. I have some and I hate wasting my -R's. I'm using gamejack and have a pioneer 106.
