which dreams do work on your system? does this happen if you use dreamscene dreams and not deskscapes? and what version driver # do you have? helps to know all details to nip this in the butt.
that dude has some freakin awesome artwork going on...
just go into your quicktime preferences and uncheck the box for run at startup if you don't want it to run when you boot...
don't know if this will appy but hey give it a shot......when you install the video drivers nvidia does not overwrite some of their own files that get put into the system32 folder and drivers folder under system32...these are the .dl files and the .sy file. try to replace those manually and reboot and see if you see a difference. also before you shut down put your screen to wallpaper instaed of dream...know a lot of people had this problem so give it a try and hope it works....but better to try
if you have iTunes without quicktime and your quicktime is an older version then you have a good chance of that being the culprit. it states for vista users to uninstall quicktime and then redownload and install the iTunes+quicktime download and that should solve your problem....found that on an iTunes forum hope that helps...
