I personally use this one and find it quite good. It comes with integrated mediaplayer classic as well:

Mediaplayer Classic is also my preffered player. Has some really great options other players don't have like stretching the picture to fit better to screen. NumLock+9 (It just cuts a bit of the sides while getting more height)
