[mythtv-users] No video on frontend

Hi!

I have a Thinkpad T61p laptop, running Ubuntu 10.10, on which I've 
installed a mythfrontend (ubuntu package). Problem is that I get nothing 
but a black screen when watching live TV or recorded programs. Audio 
works, but just at black screen.

The laptop has a Nvidia graphics card, and I run the proprietary driver 
(version current, installed through Ubuntus utility). I have switched 
off all eye-candy on the desktop (set level of effects to "no") and 
uninstalled all compiz-components and turned off composite-manager in 
metacity. Screensaver turned off.

Playing recorded programs through VLC works nicely (streaming from 
mythweb).

xvinfo gives me a lot of output, the first lines being:

magnus at pollux:~$ xvinfo
X-Video Extension version 2.2
screen #0
   Adaptor #0: "NV17 Video Texture"
     number of ports: 32
     port base: 598
     operations supported: PutImage


For mythfrontend.log see below. Any ideas on what to do, what might be 
wrong? (I've searched the mailinglist but so far have become none wiser)

Best,


Magnus Larsson
