Hey all, forgive the noob question, but a search didn't produce anything definitive. I'm looking to take the dive into a Apple TV unit. I have years worth of .mkv, avi, divx, (etc.) files and would like to stream them from my PC to the Apple TV unit. Converting all these files to iTune friendly format would be my life's work and the quality would suffer. Can this (streaming) be done? Details please for a noob!
