Some players come loaded with too many features and too many codecs - not MPCStar. MPCStar is a universal video player that can play most formats of films downloaded from the internet. MPCStar has been developed using open source libraries, so it's highly customisable if you have any programming knowledge. One of the best features however is a pop-up blocker which prevents pop-ups appearing that sometimes come loaded with films.

To ensure smooth playback and not get weighed down with too many codecs, MPCStar contains only the major codecs including Media Player Classic, FFDshow Codec Pack,
RealPlayer Codecs, ActiveX controls, QuickTime Codecs and DirectVobSub (a.k.a. VSFilter). The only problem is that these codecs are regularly updated and there appears to be no automatic update function but overall, this is one of the simplest and most powerful players I've tried since VLC player.
