hey new guy here i just got my macbook pro almost about a week ago and im having some problems with the isight and my internet connection(internet should not be the problem its working fine on my desktop and other computers on the net work)

some reason when broadcasting on my macbook with the iSight it lags out my internet
ie; on skype broadcasting and it lags the video...eventually says lost connection and hangs up.
Also on websites that have broadcasting like yahoo live i bring up my cam and it starts lagging my connection
anytips would help alot this is very annoying
Thanks Steve
