Since I like to watch my anime on my 50 tv, I had to find a way to get files to work with my apple tv since that is the way I like to watch videos and movies. Took me a little bit to get things to work right and I think I have the settings correct.. I had to convert the .MKV files to a .MP4 file. If you have a jailbroken apple tv, some .MKV may work but in my case, most won't. I use hand break for the program that converts it for you, including getting the subs on there as well. So far I haven't seen a mismatch in subs to sound or sound to video. I also haven't seen a loss in quality as well. Try it out and see if it works for you, and if something is not working right, let me know so I can update the tut. FYI, i have never made these before, so don't mind the crudeness. Also it is a 2.2meg file, I'll put it in spoiler mode though.
