I can't manage to do that. If I try to run vdr as user root, vdr-kbd 
complains to refuse to run with root priviledges. If I do "su vdr" 
whoami tells me to be still root - is that what you meant by "sux"? 
Because I don't know sux, and nothing like this is installed.

I tried:
root at linux:/usr/lib/vdr# DISPLAY=:0.0;xset s off;vdr-daemon 
--config=/var/lib/vdr --lib=/usr/lib/vdr/plugins -d
ib/vdr/plugins -vo xv:" -u vdr -g vdr
Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
xset:  unable to open display ":0.0"

as mentioned in the link you provided at the end of your posting.

BTW, is "-vo xv:" right for me? I couldn't find anything about XvMC, or 
should I better use xv with my graca, which uses v4l if I'm not 
completly wrong?

Glad to here that, so I didn't understand everything wrong ;-) That's 
exactly what I intend to do.

So I think my main problem is exporting the display right. For the time 
being I've only one display, no tv-out, which I would experiment with 
later on, when the rest is running.

But I'm not used to exporting displays and don't know how to manage it 
for the user vdr - do you still have the patience helping me again?
