I searched all over the boards and didn't find this info so hopefully I am not being redundant.

I cant figure out how to get movies I currently have in digital format to play on my PSP. What do I need to convert these files with? I've already tried PSP Video 9 and had no success. I used the PSP settings but every time I do this I get "unsupported data" error on the PSP.. Any help would be greatly appreciated. If a tutorial on this already exists I would be happy to follow any link provided! I am running Pro CFW 6.60 on a PSP 3000 if that makes any difference.
