so my dad and i each have an isight (he is using it on his 15 inch PB AL, 1.25 ghz, 1 gm RAM) and i am using it on my G5 desktop. We both have the latest versions of software, etc; i also have downloaded iGlasses to brighten things. the main problem i am having is that there is a moderate amount of pixelation of the image that i am seeing of him (and i think vice versa). for some reason, the demos in the apple store show much sharper well defined video quality. Now i realize that the Isight is not meant to be a super high quality camera, but i expected a little better. Needless to say, we are both running this on broadband internet. Just wondering if anyone has had similar experience, and if they have any luck enhancing things.
