Hi Was just wondering if somebody could help me out. I've done some searching around but havent really been able to find a definite answer. Basically im trying to play some MP4 files in Front Row, but it keeps saying that it is an unsupported format. I have Perian installed, but still no luck. Does this mean i will have to convert them in order to play? And if so what would be the best format? Sorry if this sounds like a stupid question, but i dont know a great deal when it comes to video formats/converting etc. Thanks.
