The delay is real. I can wave at the camera and count to ten before I se
e the wave on the screen. At 320x240, it's half that, and half again at 160x120.
There are no applications in between. I'm using cqcam-0.40b in Xwindows with the
tcltk interface. The system I'm trying to get working is SCO ODT-5. I have a De
bian Linux installed on a laptop also, I get the same kind of results with it.
