ubun2

Some of the 3gp files i download on the net doesn't work with the players in ubuntu. I am not hearing any sound. Some are erroring out due to codec issues. I tried playing with Movie Player, Banshee Media Player, VLC Media player, etc... Is there any good free 3gp player available for download that can any 3gp file?

I don't see any video player in ubuntu linux that supports playing .wma or .wmv format media files.
Is there any wmv/wma codec to support the same in leading media players of ubuntu?
VLC player plays most of the formats but no wmv. It would be great if they support it.

The default video player that ships with ubuntu doesn't play or support some of the video format because all i am hearing the sound and don't see any picture. Please help me with a nice video player for linux that supports most of the formats. appreciate your help
