xawtv was just the first app I recalled, the same thing happens with 
xterm.... 
Btw. I changed the permission for the video device to 666. I guess what you 
are mentioned is the more common way!? 
But then I have to change to the video group before i start xawtv, because 
users can only be in one group at time, right ?
