For music, you can try Aimp player or JetAudio(fee) and For video WinDVD pro, DivX player pro, splash player pro or light alloy(I'm using this)and GOM Player:notworthy:
Personally, I don't like others like Vlc, Potplayer, Media Player Classic and....
Most of Freeware media player sucks!if you can use the cracked version of DivX it would be good:notworthy:
