Hi,
I read your problems with the video and the iSight on the MacBook Pro is not all that good and there has been problems with video streaming. What OS X version are you running Snow Leopard or Lion? Also are you also opening photo booth and changing the settings in the tool bar (Camera). You do have to switch it from the iSight to your default web cam.
One more thing there are very few web cams that work with Mac so you have to be careful on which one you buy. I recommend the Logitech HD Pro Webcam C910. It's a great webcam for $99.00.
The other thing that also helps is Flip4Mac if you don't have it Installed. And always make sure you have enough broadband speed since video takes a lot. You can check your upload and download speed at: speakeasy.net/speedtest Also make sure you have enough memory, I recommend 6GB and no less than 4 GB with the MacBook Pro.
If anyone needs help with a MacBook, Mac Pro, iMac or any other Apple product leave me a message and I will get you the answer you need. I kind of know a lot about Apple products since i'm a developer for Apple. I also like to develop websites for Flirt 4 Free. And have to say that Flirt 4 free has the best website code, great staff and the best models on the Internet. and i say that because I have designed websites for other webcam sites and Flirt 4 free is by far the best from what I have seen. The Models are just amassing and always happy unlike other cam sites. Take care and see you all around. If you see MauiShark thats me....
