Here you can see 0/the sound card, 1/the midi controller and 2/the
webcam (Logitech Quickcam Pro 3000-2, Phillips compatible). But, when I
use xautv, for example, to see if the cam is working, it gives me the
$ xawtv
This is xawtv-3.81, running on Linux/i686 (2.4.22-6.ll.rh90)
/dev/video0 [v4l]: no overlay support

When I try to use the cam, with either xawtv or more importantly in PD
(with the PDP libraries) the video window is green. This seem to me to
be the _No overlay support_.
