Dragon Players great and I suppose it does what it sets out to do - but it's got a long way to beat VLC!

VLC and Mplayer/SMPlayer are both great.

I voted for VLC.

VLC - because it has always played what ever I've thrown at it.

Vlc works best .

VLC
 

VLC is the one application that I don't think I could live without. It is always one of the first things I install on a new system.

VLC and Xine
 

I use VLC most of the time, but sometimes the QT style settings require some tweaking to blend in with your GTK theme. Unless you use skins, in which case it doesn't matter:D When VLC isn't available, Xine works pretty well with Gxine front-end.

I would say Xine and M player

I love VLC Media Player very much.

how about UMplayer?

Video Media Player
 

VLC. No question.

VLC - it's cross-platform, without the fuss.

Kaffeine
 

VlC is a close second.

VLC has my vote.

Mplayer (smplayer)..
