Sounds like you've got the byte order wrong.  Ie, GnomeMeeting is 
expecting the bytes in R-G-B order, but the camera is sending them in 
B-G-R order.  Some programs (I'm not familiar w/ Xawtv) detect this and 
auto-correct; others (ie, GQCam) have an option to change the byte order 
in which they expect it.  I don't recall pwlib exporting functionality 
to change this, and I certainly don't see any switch in GnomeMeeting proper.

Try this:  (close all camera apps.)  Remove the ov511 driver with
   rmmod ov511
Then, re-insert it with the force_rgb flag set:
   insmod ov511 force_rgb=1

See if that helps.
