[HELP] MKV WMP Crashes [/HELP]

[|Z3R0|]

I got a few ... backup ... bluray movies on my computer in .mkv format and to read them on my computer I just downloaded a WMP community pack so that WMP would recognize the file blah blah blah. The problem I am getting though is most of them work just fine but a select few decide to rebel against me and all I get is a grey screen and a crash.
This is the crash report...

Code:

Problem signature:
  Problem Event Name:    APPCRASH

Another thing though, in one of the movies I get a grey-ish screen and sound but doesn't crash, which made me start to think that maybe it was a GPU driver issue but I have the latest driver and have tried the beta nvidia driver. I almost think it might be just because I have 64 bit or something. Not really sure how to go about fixing this but it sure is annoying to have all these movies and can't watch them.

PC Specs
Windows 7 Ultimate 64-bit
Intel Core i5-2500K OC'd @ 3.4Ghz
8GB DDR3 1666
1.5TB WD @ 6GB/sec
EVGA 570 HD
MB: Gigabyte Z68X-UD4-B3

Any help would be greatly appreciated!
Thanks,

Download VLC (http://www.videolan.org/vlc/) and the K-Lite codec pack (http://www.free-codecs.com/download/k_li...c_pack.htm).

Great combination and runs my blu-ray "backups" fine on my iMac boot camp.
