Presumably there are some settings for the webcam such as resolution. Do you have the same ones as in the old PC? There could be default settings for the camera and settings for the web application you are using.

yes there are settings... res is the size of the image not the grainy junk.

this is what im talking about:
Grainy: http://vinaynag.files.wordpress.com/2010/06/grainy.jpg
VS
Normal: http://2.bp.blogspot.com/_LNKl24iTwzA/TOwetyMxWcI/AAAAAAAAAt4/cA9zK5sV34w/s1600/social+media+control.png

my webcam should be a HP Webcam HD-2200 if that helps...

The two pics are somewhat awkward to compare, jpg v png, almost monochrome v colour, differences in size. There is however a visible difference! My first impression was that the grainy picture looked like the image had been digitally zoomed, only part of the picture area being used. Cameras that have an optical zoom will use the full 1280x720. If the camera is 1280x720 and the digital zoom set for the camera is 5x, then the actual picture area used is 256x144. That is then enlarged to 1280x720 and looks fairly horrible. Does zooming ring a bell?

zoom is greyed out and cant seem to click it... i am not sure what i did but i got it to look ok... the FPS seems to be a bit slow still but at least doesn't look like your watching a channel with a weak signal.
