Please remember that if you are going to make a Dream out of someone else's video (i.e. Blizzard's), you need to make sure it meets the following rules before uploading it to WinCustomize:

Must be less than 25% of the length of the original video

OR

Must be less than 15 seconds of the original video.

Whichever results in the shortest segment.  So for a 3 min movie, you could get a 15 second clip.  For a 30 second movie, you could get a 7.5 second clip.  This is to protect the rights of the creator.
