Ok, so I got me the 4GB Sony MemoryStick PRO DUO MagicGate and for some reason, videos will only play for about 10 seconds when they stop and a message saying "this video cannot be played" appears and I cannot longer whatch the video. What's weird is that I have the smaller 32MB memory stick and it works fine. I've tried converting the videos using CloneDVD Mobile, PSPv9 and PSP Max Media Manager...all with the same result..10 seconds of video playback..message appears...I'm screwed. Any idea why these videos won't work with the 4GB card, but will with the 32MB one? I have the latest firmware for the console too. Any help will be appreciated. Thanks.
