The XVideo uses the v4l bridge functionality of the v4l X-Server module (grab 
from v4l and display using Xv). This is basically the same that kdetv's v4l 
plugins do. But the V4L bridge does the initialization right while kdetv does 
not. Read the manual sections about the plugins, there is a better 
explanation.
