I just got a new Dell Latitude D810. It absolutely flies. However, I was getting very weird playback when playing certain WMV files (e.g. ECO is Child's Play or the PDC sessions). The playback was twinged with orange, and lime green, and other colors where I couldn't see the video. I felt like firing up some Jefferson Airplane to complete the effect.

To solve this, I ended up opening WMP9, going to Tools | Options | Performance and turned the Video acceleration setting down to None. Problem solved.
