1)I made a mistake in my original response, and thought I had corrected it: Rather than calling the Microsoft product "Windows(TM)Utimate Extras Dreamscene", as it should be, I called it "Windows DreamScapes". This probably caused some confusion, since the two titles "DreamScene" (Microsoft) and "DeskScapes" sound so similar.
2) Until I got "Windows(TM) Dreamscene" properly installed on my Vista Ultimate SP1 RC1 Refresh build, I was unable to use Stardock's(TM) "DeskScapes", which is supplied with Object Desktop Network Edition. They would start, run a few seconds, then suddenly stop. Since I've got all things straightened out, they run magnificently together.
3) If I try downloading any DeskScapes from WinCustomize under XP or Vista Home Premium, I am told either by Stardock Central/WinCustomize that such downloads are ONLY for those who have Vista Ultimate, and they simply refuse to be downloaded or installed.
4) ALL of this leads me to believe the following:
To install and use Stardock's DeskScapes one must have Vista Ultimate w/Ultimate extras, including "Windows Dreamscenes", installed.
As to the various formats which either Stardock DeskScapes or Windows Dreamscene use, below are a small list:
Stardock DeskScapes: *.dream (I don't know of any other formats it will use. I think it uses its own media engine? PLEASE correct me, if I am wrong.
[There is a check box to use either the Internal Player (whether this is Microsoft's or Stardock's, I know not) or another(I suspect this means the active or default engine, since I've changed it to QuickTime before, and all the video icons became QuickTime icons.)]
Windows Dreamscenes: *.mpg, *.avi, *wmv (It will probably use almost any format Windows Media Player will recognize and play, since it uses (by default) the Windows Media Player engine)
I don't know whether or not these formats are interchangable between WMP/WMC and Stardock DeskScapes. I suspect this is probably so, IF one with such formats are wrapped up into a *.dream file.
