Hi, I have a very annoying problem with my psp 3004 lite. When i play games like monster hunter 3rd or god of war every intro and in-game video malfunctions after a few second. A 2 minute video takes 10 min. I use CFW 6.20 A-Hen and i've already checked the VHS settings ( they are on 333 ). How can i solve this? Please help.
