Xine/Mplayer can't use xv

[Tom Chance <lists@tomchance.org.uk>]

Hello,

I've got an install of Debian sid (unstable) with Xfree 4.3.0.1, an nvidia 
card and the latest builds of mplayer and xine. Neither can use the "xv" 
extension. When I try, I get the following errors:

With mplayer:

Xlib:  extension "XFree86-VidModeExtension" missing on display ":0.0".
vo: X11 running at 1024x768 with depth 24 and 32 bpp (":0.0" => local display)
Xlib:  extension "XVideo" missing on display ":0.0".
Sorry, Xv not supported by this X11 version/driver
******** Try with  -vo x11  or  -vo sdl  *********
Error opening/initializing the selected video_out (-vo) device.


With xine:

Xlib:  extension "SHAPE" missing on display ":0.0".
Xlib:  extension "XVideo" missing on display ":0.0".
main: video driver <xv> failed

I know I could use the X11 or SDL video drivers, but they lack functionality 
and performance; you really need the xv extensions for good video playback.

I read in an Mplayer HOWTO for Debian [1] that "in unstable xv might not work 
properly as a video output".

How can I fix this?

Regards,
Tom
