I looked at that TechTV article, and it assumes you're using a flatbed scanner and therefore all the images have edges that properly match. Unfortunately, it doesn't apply here.

When you're doing photos, the edges of each image need to be stretched and distorted so that they match up. The more variation in the rotation and angle of each photo, the more each image needs to be distorted. That was something I liked about the Canon software, it did a really good job of handling this as well as giving you control over the matching points.

Can't compare it to the photoshop CS feature since I don't have it....
