I would like to experiment myself, it kind of looks like fun. So are the 2006 dvd's the best source to work with? Are they better than the laser discs?

I hear ya, Brooks. I've been the same way. As much as I love and respect everyone else's projects, there's just something about the personal touch.

For my money, the '06 DVDs are the best to work with at the moment and are what I've used for the bulk of my custom sets. While they're based on the same masters from the 93/95 LDs, there are some differences (i.e. missing scanlines on the Emperor hologram). The NTSC versions are best for ANH and ESB. The PAL version of ROTJ is superior, but only slightly.

Laserdiscs, in my opinion, have been more useful for their sound mixes than video (though they are the best source I'm aware of for the "Episode IV" crawl).

Unfortunately, every official source has something wrong with it (Lucasfilm did a real bang-up job over the years), so what starts as "fun" might end in "frustration". Best of luck! :)
