"SpursEngine and give HD out of existing DVDs"....this is flat out impossible. It can make SD look the best as it can on HD screens but compared to true HD sources, nothing will compare (as long as the HD encode is high quality).
The effect is easily demonstrated. Using your favorite image editor (I like GIMP( gimp.org). Take a full 1080 HD (1920×1080) image, use the scaling feature to scale it down to SD resolution (480 vertical resolution, keep the same aspect ratio). Save it as a new image. Now take the SD version of the image and using the best scaling method possible (experiment with different settings) and scale it back up to the HD resolution.
Flipping back and forth at the native resolution (use a proper monitor), you will instantly notice the loss of crisp detail. This is an example of how upconverting or upscaling an image cannot ever have the same detail and clarity of a true native HD image....

Use this image as an example: http://interfacelift.com/wallpaper/downloads/01548_stpaulscathedral_1920x1080.jpg
This image has nice detail especially around the cathedral dome (notice the railings)
