HI. I have a version 7 ps2 and have a problem of my backup games (so far nfs undergrond, kingdom hearts). For some reason they hang or freeze at the loading screen, and loaded up to this point. I had used different dvd-rs before but am not sure if its the new memorex version 2.0 discs that are causing the problem. If this is the case please refer me to some dvd-rs that work with my ps2 and are realivity low in price. I would prefer being able to go to a store to get these as i am in a hurry.
