И у мя тоже не работает xv.

А не работает вот что, вместо картинки при выборе xv я вижу синий экран, при этом звук есть.
Так же всё работает на x11.

Вот что нашёл сдесь:

/*********************************************/
попробуй xvinfo - а есть ли он у тебя вообще?

если есть то

mplayer -vo xv

без g - как работает?
