V4 ps2 ng with Infinity Modchip

[Glock_23]

I have installed a Matrix Infinity 1.38 in my v4 ng ps2 and everything works perfectly except ps2 dvd-r backup games.
When I tried to boot a dvd-r backup, my ps2 started clicking and grinding and get "disc read error" in the browser.
I know it's not the installation problem cuz I can get into Infintiy option configuration menu and Upgrading Infinity FW.
Already upgraded to 1.39 FW and still get the same error problem..........

Is this a defected chip?
Has anyone had experience with this kind of problem before? Help..
