Hi, Is anyone using the set up of playing your movies in itunes from a hard drive that is connected to an airport extreme base station. I am trying to do this but they are lagging a bit. Ideally i want to create a movie collection and store it all on the external hard-drive so not to take up space on my mac book pro, but i dont want an external hard-drive plugged into my mac either so i figured this would be the best way to go about it. Am i asking too much here? Also if i buy an apple tv in future will it stream the films off the hard drive without my macbook being turned on? Finally my last question is this. My movies are in .mkv format. What is the best file format to convert them too to keep the 720p quality? Or should i just choose save as in quicktime and save a reference file for itunes to point too. That way i dont have to convert them then but am not sure if this will work with apple tv. Sorry if i have babbled on a bit i hope someone can help me.
