Hi All I've just replaced my Apple TV with a PS3. All my videos (personal DVD collection) don't work with the PS3, I'm very annoyed as they are MP4 files and SHOULD work!!!!). I've tried a thousand different things (change header with PTPro, renaming files, etc) but with no luck. I've accepted that I'm going to have rip and convert my entire video collection again. So to avoid this in future, what is the best video format to go for? What format is likely to be future proof?? Divx? Essentially, what will work on the PS3 and AppleTV (the Apple tv is going upstairs!). Thanks for your help.
