I apologise as I realise this question has probably been asked quite a lot, but I hope someone can help me. If I was to buy a Time Capsule and Apple TV to hook up to my MBP, what would be the best way/app to configure it so that I could directly stream videos from my MBP/TC to the ATV without converting them to mp4/buying through iTunes (ie. playing AVI, MKV, MPEG, FLV, F4V etc. files)? I take it this is not possible to do natively. So are there hacks or third party apps that allow you to do this? And how reliable/effective are they? Many thanks for your help.
