After a great deal of pain in the butt (and tinkering around with two different third party programs used together), I've been able to successfully rip a crystal-clear, 720p HD video of the ion cannon from Command & Conquer 3's game DVD.
I hope those images aren't representative of the actual video quality (which RS is too busy to let me download) because I don't think you can reasonably describe them as "crystal-clear".
