Gnome-MPlayer is not in the list, so I'll vote for MPlayer

I use VLC on all platforms.

VLC mostly, or mplayer

Kind of hard, VLC, Totem, Mplayer depending on specific content, each has it's sweet spots.

Pure, unadulterated mplayer. :)

If you need a GUI frontend, UMPlayer, gnome-mplayer or SMPlayer would do. With proper codecs (eg: gstreamer-ffmpeg) Totem also works for me.

Voted VLC though I tend to use Kaffeine out of habit.

VLC or Kaffeine. My vote for VLC though...

VLC, for no hassle with codec installation.

VLC player rocks. It is the best out of all the Linux media players.

No Parole? It is the default for Xfce.

Parole has been added.

Yup, VLC, but I also like and use:

mplayer (This just goes w/o saying doesn't it?)
xine
kaffeine
Dragon Player

VLC. Saves me headache. I already have enough to worry about as it stands let alone trying to figure out why I can't properly load a stream from my media server. It just works.

no comparision with mplayer tui ..
