I was trying to watch a movie on my PS3 from a USB. The box states that it supports multiple formats but it doesn't say which ones exactly. I converted it from the natural HD format (****hd or something) to AVI to mp4 and I still have many formats to try. I click on the video tab and slide to USB and it says "no files" or something. Does it have to do with the resolution or something or can you just not play videos from USB? It's capable of blu ray playback and regular DVD's so I find it hard to believe that it doesn't support USB files. Does anyone know what to do?
