I am using this, and I have no problems with its editing functions or DVD authoring at all. However, as I am trying to re-edit videos for the web, and I am adding a watermark I am having a problem.

For instance, if I 'Make Movie' without a watermark the size of the file is 718.8 MB

If I make the same movie WITH a watermark it is coming up to being 5.7 GB

Does anyone have any idea what is going on with this, and why it is making the files so big just because of a watermark?
