video file playing in debian?

[Karen Lewellen]

Hi all,
granted I am still at the document reading stage, creating issues with my 
install.
Once there tough I am wondering what I can use for playing files I get 
from say youtube and other locations?
we have a terrific program on shellworld for getting them,
its called movgrab.
but once I get the program from my shellworld space to my machine running 
debian, how will I play it?
something command line, like the audio player I use in  dos, mpxplay would 
be terrific.
Thanks,
Karen
