so ive just learnt that you can copy and paste films youve downloaded from your computer onto your ps3 via a usb, but for some reason when i go to test the film out on my ps3 it goes unsupported data.

now i know the ps3 only supports some file types but when i go to put some films on it just says unsupported data, i then compare the one that didnt work with ones that have and they both have the same info i.e. MPEG4, AVI, etc

does anyone know what is wrong or a solution?
