CCCP Media Player

Black Hole

May contain traces of nut
Not tried it myself, but mentioned in Windows Help & Advice magazine this month is the Combined Community Codec Pack, which is now "a fully featured player unto itself. It contains all the necessities you need to play just about any file you can throw at it, it's small and doesn't use up much memory, and we've found it to be more stable than both WMP and VLC."

An advantage of VLC is that it can access DLNA sources - not sure about CCCP.
