MPC-HC, MPC-BE, PotPlayer. Those are the only ones you should consider using on Windows. VLC is 
only relevant if you're on Linux or Mac.

DaumPlayer is way better than VLC, but MPC-HC / BE (your preference, really. I use HC for RAR packed 
files, it deals with those better than BE, since it has a modded RARFileSource filter internalized, 
and BE for everything else).
