Thanks for the replies. The one that I have was called "Illuminations Remix" and is just under 50mb and is about 13 minutes long. It was done by someone from a couple of filmings and then mixed with the music. Came off of a server from Univ. of Chicago if I remember correctly, but I've slept a lot since then.
I did find one this morning on the WDWMagic site but you have to pay a monthly fee to download the videos. It is about 153mb for about 15 minutes so I would assume that it is a much higher quality.
I am going to join for a month, about $4, so that I can download it and check it out.
U P D A T E ! !
Well, just blew $3.50. Saw the video that was supposed to be high resolution and while it was a bit better than the one that I have, it had none of the music on it, just a bunch of oohs and aahs everytime the fireworks went off.
Oh well, I've used the one that I have quite a lot so I guess I will just keep it.
Thanks again for your help.
