After fiddling around with dreamscene I realised I had some trek avi's. Very short about a minute or 2 long. I converted them to wmv.
So if your a Star Trek fan and want a new dreamscene BG, try these!

OHH WICKED THANKS

Oh well. At least one enjoyed it

I don't have vista, so no dream scene, but I can also tell you that's awesome!

would you be able to make some that has the DS9 logo in it and the defiant flying round it?

a sample from the opening credits?

I take no credit for the creation of the files. I got them from a website years back. I just converted it to a compatible format.
