New to Macs...got an iMac @1 month ago - love it! Looking into extending the use of media. Would like to use my iMac as my 'central' device (music, photos, movies) but have the ability to tap into my home theater system (HDtv, 5.1 audio). Used to have xbox media center plugged into my home PC and enjoyed being able to get content from my PC to the TV. Is Apple TV the best solution? or is a media server (Plex or something) a better alternative? I don't use Netflix/blockbuster/Roku... but I do have a library of movies, music, photos available on my iMac. My iMac is on my main level - home theater is in basement. Looks like I can do wireless with Apple TV or I would have @50-60 foot run if hardwire is needed.
