Green Preview Window

When I import either a DVR-MS file or video direct from a camera the preview
is green so it's impossible to do any editing. The thumbnails display
correctly. When I did a test export the resulting WMV file plays perfectly
in Media Player. I've tried disabling all the codecs in the options menu and
trying each individually and some options will give me a black preview as
opposed to green. Any suggestions as to what I can try?

Thanks - but I just solved this problem by installing Catalyst 7.6! Wow 7.5
was only released about a month ago!
