Thx a lot.. i already give up for this problem... look like no solution...
now is the webcam problem...
my old inspiron 1520 webcam video quality is much better than the current studio xps 16 webcam video quality
when video call using Windows Live Messenger... i know, both is 2.0MP webcam...
i check the 1520, the driver use year 2006 Microsoft driver... and the current 1640 use latest Creative Labs driver
then i uninstall the Creative Labs driver, and let the windows 7 self install it.. now using year 2006 Microsoft driver..
The result : still the same bad quality.. some time freeze...
then i reinstall the latest Creative Labs driver... Now, no more freeze, jz bad quality.. can see a lot of boxes
WLM version same... use same connection... at home...
If the video quality is bad, i.e. pixelated video, video feed from the person on the other side froze then it's very likely the Internet connection is slow; whether it's the Internet connection on your side or the one you're trying to communicate with.
It happened to me when I was in Australia, video chatting using LiveMessenger with my friends back in Malaysia. It doesn't happen all the time, if the connection is good then the video quality is good and vice versa.
Switching to Skype improves the situation a bit.
