MeGUI & PSP

I have 3.03 OE-C version. And whenever I encode any video using MeGUI 2.0 and put on PSP, it says 'Unsupported Data'. I tried to change resolution and other settings but PSP behaved same.

Do you guys have any guide for encoding with MeGUI for noobs?

Please. And also that how can I play 480x272 video on 3.03 OE-C?

Thanks.

I always recommend XviD4PSP as a video converter for both PSP and iPod. It has supported conversion to full resolution since it was implemented in 3.03 OE-B, so it follows the homebrew scene. It's free, and absolutely the best choice in my opinion. But if you want to stick with MeGUI for PSP conversion, I can't help you.
