Also, this is dual layered which means there is no compression artifacting, whereas you get the occassional artifacts in DVD-5s. The one area where this version falls behind others is in having little to no anti-aliasing work done, although I don't think the anti-aliasing filters on the other projects ever completely solved the matter. The other ones have the stereo mix AFAIK, which I enjoy the most and miss here.

Dark_Jedi's GOUT restoration is also a DVD-9 and has 5.1.
