I'm wondering how to convert .mov to .mp4 (obviously ). I've tried a number of programs, but apparently 3gp converter is the only one that can convert .mov files, however I get a 'codec error' saying it's an unknown codec, or something, whenever I try to convert. I can convert from pretty much any other file format with PSP Video 9, but I've a load of stuff (mainly Clone Wars, some short movies etc) in .mov format. I'm aware that they use the same try of compression and that they are similar files, so if anyone can help, it'd be appreciated. Thanks.
