Why has my video quality deterioted after installing Vista SP1 RC?

[Martin]

After installing Vista SP1 RC today my video quality has deteriorated. I have
unistalled and then reinstalled my Nvidia 7800 GTX card and drivers after
using Driver Seep to get rid of all old drivers. I get a jerky video in .wmv
and .avi videos in WMP11 and I also get faint vertical lines on videos in VLC
Media Player. There is also a discernable quality loss in Quicktime movies of
all kind even the h1080p size.

I even went through the pain of uninstalling SP1 RC to verify that something
else wasn't wrong!

This is very frustrating as this would be the last type of problem I thought
I would encounter after installing Vista SP1 RC!

Any help, fixes or acknowledgement that this is a know problem would be
great!

Remember that SP1 is still essentially in 'test' mode until the release of
the RTM. You might also want to make nVidia aware of your problems..
