XBox has too less video memory (4MB) to use 1024x768 with double
buffering. Either disable double-buffering in MPlayer or use a lower
resolution. It should be also possible to increase the aumount of memory
reserved for video to 8MB from the kernel, but I don't known exactly how.

Probably you have two versions of DirectFB installed and MPlayer is
linked to the older one.
