pulsing blur on playback

[scottishguy67]

Hi
wasnt sure if this was os specific so posting here.
when viewing a movie or any video on vlc, there seems to be a frequent slight blurring of the image every second or so.
This seems to be consistent with any movie file that I play.
im using vlc at the default settings on a dell precision m6400 with nvidia quadro fx 3700 card on win7 pro 64 bit.
has anyone else come across this issue and if so is there a solution?

it doesnt make the video content unwatchable but its one of those things when you have noticed it you keep noticing it.

Thanks

G
