PS2 Ritek Problem

[boofs_Magee]

I bought the 100-pack Ritek G04 Silver Shiny DVD-R from www.meritline.com , I used them in my one friends ps2, his is a version 5, and it worked. Booted up w/ swap disk blue screen. Now when I played the same game on my other buddies ps2 version 3 ritek G04 wouldn't boot. When swap disk loaded had green outer screen then blue, not blue right away. And the game never finished loading, it just froze. Is this because of the DVD drives in the different version; one is newer and more compatible with wide variety of DVD's? The whole version for this post is if anyone has had this problem, I hear everyone always talking about Ritek's being the best. I have a version 4 ps2 and these are my games, are the version 3, 4 and 5 use different drives? Haven't tried on mine due to the repairs needed. Can anyone help? Thanks
