On the subject of the KMPlayer, does anybody know of a good optimization guide? I googled a bit and didn't find much useful info. In my case, I am using the "Preset: Quality (3GHz)" setting, but as noted there are a ton of options regarding post-processing, sharpening, etc. If the OP wanted options, then he could easily spend days sifting through this amazing player.
FYI: I'm probably the last person to find out, but I just recently discovered KMPlayer also will display your pics-- a true multimedia player!
