It works ... and no !

On one system, I have an IVTV card, but also a webcam.

Here is the result :

On another system, I have a working DVB-T usb adapter
(working under 
kaffeine -I'm on Mandriva - and under freevo).
The result is even worse (but I think you allready know
that) :

Thanks,

Webcam drivers support v4l2 but you need to get the correct
driver. A 
lot of webcams use the Philips chips and the best v4l2
driver is at:

.de/ and http://www.saillar

There is no directory for video4linux which possibly means
that this 
machine is using an older kernel.
