If you have DreamScene installed and have already updated it, then do you not already have the extra updates for it?
I'm afraid I do not understand what your problem is since you say you have it.
You might consider using DeskScapes instead.
How to Enhance Windows Vista DreamScene with Stardock DeskScapes
I too have DreamScene in installed and works fine. My problem is that I do not see the pictures of the video on the icons, all I get is a DVD disk that shows that it is a media file. This is probably a codec issue but I have installed all the Video codecs that I can get my hands on? any ideas?
I am running Vista x64 Ultimate on a ASUS P5E3 Delux M/board. 4 Gigs of DDR-3 with the Intel Q6600 Quad 2.4 CPU.
