well for us anime fans that like to torrent anime, alot of fansubbers are usings a new coddec called 10-bit
the problem is that this is a new thing and alot of good .MKV players dont have what it takes to run a 10-bit, unless you go and add the right filtters and splitters and codec packs you need. the best thing to do is download 3rd part players like "M2Player, VLC,BSplayer"
i my self like to use MPC-HC and had to download alot of packs and things to get it to work but it seems that MPC just doesnt work.
but i found a way to get 10-bit anime to work sadly this is for user that have media center.
you'll have to download the K-Light 64bit full codec pack and set all that up and update your media center fully, and after all tha t it should work fine.
go to this page for help on how to set up MPC: http://wiki.bakabt.me/index.php/Hi10P
here is k-light: http://fileforum.betanews.com/detail/KLite-Codec-Pack-64bit/1094057842/5

also note: the only real dif with 8-bit and 10-bit is " 10-bit is a little more colorful " dam thos otaku baka for making it so hard to watch anime on PC now rawr
also this all aplys to ppl that download and watch anime on PCs
