Yesterday after I got back from work and grabbed the update I noticed a lot of odd flickering in games 
It's really noticeable in PGR3 and somewhat obvious in Full Auto & NBA 2K6 - a fault of the update or my 360 starting to die?
The flickering appears in big horizontal stripes across the screen. Using a Sammy 32" R41 model screen with the xbox connected through VGA
Any ideas? Could really do without this as it's affecting my enjoyment of nearly beating my mate on NBA 2K6 :>
