Two things that spring to mind..
1. Do a google search for your camera. I had a lend of a camera a while
back (last time the expo was on) and turns out there were two versions
of it. The one with the black case wasn't supported AFAIR.
2. It might be X. Try it on a box with Xfree86 3.3.X and the XVideo
I had problems getting X and RH7.1 to display any picture using
"mplayer" until I messed with the yuv settings. (that would be "mplayer
-vo sdl -yuv yuv file.avi" for the rest of you, or something very
similar, I may get it confused with another player.)
Do "xdpyinfo|grep -i xvideo" and even if it shows it's loaded it might
not work without a bit of nudging. XVideo is loaded on the box at home
yet I still had to do the above tweaking.
