Code:
X11 error: BadAlloc (insufficient resources for operation)?,?% 0 0
Uh oh! It looks like its your Xserver.... bad.. It looks like its reporting a problem related to memory not availible. Do you have another graphics card etc? Other than that... X.org updates MIGHT help.. But then you would probably suffer dependency hell. have you tried a lower resolution? (Via SaX2, change the moniter to Vesa, and select a resolution and it will force it, and then change the resolution to whatever you choose for the moniter.)
think a lower res would take less memory. You could consider upgrading your pc a bit, but it would piss you (and me if i were you) to buy something if it didn't work...
I run my linux box for extremely long piriods of time and after a while it might start giving this error along with some really weird artifacts on the screen.
Hope you figure it out. If you get the mplayer gui, find settings and look for the video out. Change it to something else and it might fix the prob. In console mplayer, i only know how to play a video. I think the -vo param specifies the video out used, but i dont remember what the possible values are. Good luck.
