Dark videos

So I had just reformatted my HDD and while trying to watch a video I noticed that it's VERY dark, almost a black screen.  Some of the videos will play fine and the audio for all of them will play fine.  I've tried using zoom player and WMP, I didn't have this problem before but I don't remember exactly what codecs I had installed.  Currently I have the combined community codec pack and an OGG codec installed.

Any pointers on what I'm missing?

turn up brightness? gamma values?
