I can do avi's. I am looking for how I can do ogm's or mkv's. Since A LOT of my anime that I haven't seen yet is in dual audio format. Is there any program that converts ogm's or mkv's into mp4's? I don't mind if I can only have one audio on the mp4. Its just that I have lots of lessons were I learn nothing so I wanted to watch anime on my PSP.
