ps2 backup problem

[matt1]

I'm trying to back up my dvd games using a sony dru500a burner without success. I'm using the swap method to load my backup & when the backup disc is in I get a blank screen but can hear the disc spinning(it sounds like it's pulse spinning). I'm using recordnow max and have a v4 with neo4 chip. The other thing is I have been using -rw & +rw media(laser & traxdata brand). Is this the problem???? I have read that rw's don't read on ps2's. Is this true???

Can anyone help????
