Video shows up dark
 

I just reformated my computer so I just installed MPC and Defiler pack. However, all my videos show up really dark. I tried with all the other video files I had with the same results.

Edit: Ok this is weird. If I have two different players (Windows Media Player and Media Player Classic) running the same video one shows up really dark and the other one just the right brightness. What gives?

This is really weird. I just restored my old settings from NVIDIA settings and everything is fixed. I dont' get codecs.
