So what I ended up doing was downloading Plex on my ATV and on my MacBook Pro, as many of you suggested. All I have to say is, wow! That service is awesome. I downloaded it on both devices, and boom. All my movies were instantly setup in a media server that I didn't have to lift a finger to create. I think my two favorite features so far are being able to remotely stream your content while not at home, and how it automatically updates your movie files with the poster art. However, I noticed it doesn't do that for all the movies. Has anyone else who is using Plex experienced this as well? Also since my content is on an external hard drive that connects to my MacBook, I can't stream things remotely if I have my MacBook on me while out and about. I think eventually I will have to maybe buy an somewhat old, cheap Mac Mini to use just as a media server, as some of you have said you've done with other Mac desktops.
