I recently purchased and put together a new HTPC. Whenever i play a 1080p MKV file, regardless of the player I use, I get pixelation in the play back. As far as I know I have the most up to date drivers to everything. I even downloaded and installed the intel Drivers update Utility to make sure. I know the files aren't the issue as they play fine on my other PC.
Any help would be greatly appreciated. Iv already spent many hrs on this trying to figure it and to no avail.

Probably you have a buggy, broken file if all players give you a pixelated playback or your players are not configured properly.
Can you upload the file or a sample of that file ?
