I've been using http://mplayerx.org/ exclusively. It seems to handle files better than vlc for me, and has a nicer mac like player.

That player has a nice GUI but renders colors incorrectly with common h264 HD videos that use planar YUV colorspace (pretty much all of them use it).

It always uses the BT.601 colormatrix to perform the YUV -> RGB colorspace conversion. While for HD material one should use the BT.709 colormatrix.

In practice you will notice darker reds that are closer to purple for this implementation error.
