I worked on a private Avatar project myself before I got distracted by another project which consumed 6 months of my life. I also got the very nice looking 1080p upscale and tried to make it the ultmate german version (with german and english audio tracks, all commentary tracks and subtitles for english, german and commentaries). Now I’ll wait what the blu-ray provides and maybe get back to it.

What’s interesting is that there’s no difference in speed between the PAL and NTSC release.
