I'm using the atrpms version of gspcav1 driver, so I can't bother him with this. OTOH, I'm not so sure now that it is a driver issue, as I find that ekiga gives me much better colour than aMSN. Reasonably accurate, certainly acceptable. What *may* be a driver issue, though, is that the parameters I should be able to set in ekiga, kopete and aMSN don't move at all. Anne
