Dreamscene not working

Hi there,

I have a new computer (Built myself) with Windows Ultimate 64bit, ATI 4870
Graphics card, Intel Quad Core. etc.

For some reason my dreamscene is not working. When I select a dreamscene for
playing, it just turnes the background black and the play option is grayed
out.

Things I have already checked:

1. Aeroglass is already turned on
2. I've tried installing several codec packs to include K-lite and a couple
different Vista codec packs.
3. Converting the MPEGs into MWV's and other formats


Thanks for the help.
