i always use a software to convert it to mp4. Usually mkv file is high definition video, rite? so you have to choose appropriate software to make sure the quality is flawless. The software is simple, choose your input, ad choose your output. that is all. and no loss on quality of the video. but if the video is big, it will automatically split the file into 2 (not compress it) as xbox only can play video file up to 4 GB only. check out xenonmkv. it's free.

make sure you check out the option too.
