First of all met me just say sorry if I have posted this in the wrong forum, I don't really know where it should go so feel free to move it to a more appropriate forum if needs be. My question is a fairly simple one. Is there a common video format that the iPhone, PS3 and Xbox 360 can all play? I have just bought an iPhone and its pretty annoying with the fact some files can be played on it, some can't, some can be played on PS3, some can't etc. Now I know this isn't a PS3/Xbox forum and I know all systems have there own supported video files, but I was just wandering if anyone knows of any profile I can use to convert all my video (except iTunes purchased of course) because at the moment its mix and match on what will stream/play on certain devices and I would prefer not to have several versions of each video because of hard drive space. I would be grateful for any help or suggestions. Thank you.
