Hello, Currently, I'm running a Apple TV 3 to my IMac. I have built a htpc because I ran out of room to house my 10 tb of movies and I would like them all to be in ITunes. All the files are in the ITunes format. I have put all of my movies on the new HTPC (windows 7), onto the 4 separate hard drives (one hard drive is A-E, one hard drive is F-L, one hard drive is M-S and one had drive is T-Z), but wanted to know what my next steps are to load those movies into ITunes, have home sharing available for all computers to watch these movies, and work through my apple tv connected to my tv. Since I have movies on four separate hard drives, do I need to so something with the advanced tab so they don't load into my hard drive that house the operation system? I just want to make sure that I'm doing the right thing and don't screw up. If anyone has an easier way, please let me know.
