sniper Modchip doesn't work with GAP-Bios!

[Murks83]

I need help!!!!
I got a PS2 with the Sniper-Modchip and a GAP-Bios onboard.
And here's the problem: My DVD-RIP CDs don't work on it!!!
I've already tried all kind of combinations of resetting my PS2 and using swap-tricks, and that shit doesn't work! I think I'll go crazy!
Can anyone tell me how I'll get my RIPs working? I've spent so much money for that chip, Pleeeeeeeeeeeeeeeeeez help me!

What does work please?

What exactly happens with the rips?

[Murks83]

I can play normal PS and PS2 games and DVDs (Videos) but when I insert my CD with a DVD-Rip there are many things that happen but it doesn't work!
These different things happen:
1.Sometimes the PS2 reads the CD and then a blank screen remains.
2.The PS2 boots till the Playstation2 logo and then a blank screen remains.
3.The doesn't boot, there's only the PS2 Main-Menu appearing on the screen.
4.The PS2 tries to boot the CD but then it recognizes that there is no valid PS /PS2 DVD/CD in the PS2 drive

When trying to read the CD there's also coming a big noise from the PS2 drive, I only knew from my PC-CD Rom drive. But that sound only occurs when I insert my DVD-Rip CDs!
What is it all about?

We need to get to a controlled situation to know what the chip is doing. Your options are:

1. Get a non-rip backup that is known to work elsewhere and try that
2. Get an import original and try that
3. Try your rip in a PS2 that is known to work with any modchip and rips

That should point to the answer. A naff rip is not out of the question.

None of the backups or original imports work!
