Harmy's work is based on the 2004 HD master that was "cleaned up" by a company called Lowry Digital. The clean up process had several unwanted effects, star fields, laser bolts and natural atmospheric diffusion (e.g. smoke or fog) were identified as dirt and reduced/removed. Harmy did pretty will getting the stars and laser bolts back, but the last one is very difficult if not impossible to undo. And unfortunately, once you've seen this effect it tends to bug you.
Team Blu's project is based off the 1993 SD master used for the Def Col LD release and also the 2006 DVD. While they've done a great job getting the most out of this source, it does suffer from it's own problems - aliasing and excessive DVNR.
It makes you angry that there is no official option to watch these films in the best quality.
Of course there's the Team Negative1 effort to scan an actual film print, but well... Negative1 can be a little, erm... eccentric (he has a track record of starting threads or blogs then deleting all content, not to mention his posting style). Still, it sounds like he may have help from some other knowledgeable people in the team, so there is perhaps some hope that this will come to fruition some day.
