zombie84: I think you're right about the degraining issue in home video releases. Here's why I'd still prefer the "clean" approach with GOUT: this noise filter they applied for the laserdisc back in 1993 seems to be a temporal one, which means it compared neighbor frames to figure out what is noise and what's detail. The result sux, and it's negative effect is present on every frame, although sometimes it isn't very visible. So the filter created this static layer of artifacts on top of the "cleaned" image. Every time the camera moves, you see these remains of past frames. Even if these artifacts contains the trace of film grain or just dirt, I think at this point it's not valid image content and better to get rid of it. Having said that, G-Force's script can't do it perfectly, so it's still a compromise.
But as you said, it's good to have different versions of this thing, and I'd say everyone should take a look on this new EditDroid disc.
Too bad we're stuck with the GOUT as the main source. (It's the root of lots of evil. :) )
