It seems there is no Xvideo support for your video card available.
Run 'xvinfo' to verify its Xv support and read DOCS/HTML/en/video.html#xv!
See 'mplayer -vo help' for other (non-xv) video out drivers. Try -vo x11

Did you try running 'xvinfo', reading DOCS/HTML/en/video.html#xv, using 'mplayer -vo help' or 'mplayer -vo x11' as it suggests? If so, what were the results?

when i ran xvinfo this is what i got

X-Video Extension version 2.2
screen #0
no adaptors present

when i ran mplayer -vo helpi got this

Does it work to use -vo x11? That seems like the most fail-safe choice. You could also try running 'gmplayer', which gives you a GUI that you can use to launch a preferences window, and try other video drivers. I'm not sure of the reasons for why xv wouldn't work; maybe it has something to do with your video drivers being out of date or incompatible. Anyway, try with -vo x11 and see if that helps.

hey i tryed it useing -vo x11 and it work, thanks a tune, i didn't realise that another option was mplayer -vo x11 "/hdd/movie/Ghost in the darkness.avi" so it's all good, thanks!
