Sadly i never have gotten rid of my fan preservation discs so much as they have succumbed to laser rot or the dye layer has failed. The worst of which happens to be my fave disc. The Dark Jedi Star Wars 1985 CAV laserdisc transfer. It is terribly ironic too because my laserdisc copy is almost no longer readable in certain sections, and the dvd was my backup.
I'm surprised your fan made dvd's have degraded already. The bootleg set I got in 2005 (it wasn't editdroid, don't have that nor do I have any laserdiscs) for me is holding up fine. Now I actually put printed labels on to them which made them not play all the way through. Star Wars also got scratched by a rock in a portable dvd player (the scratch is circular so it only affects the Yavin battle of the movie).
About a year ago, I was able to copy every disc with the label intact (except for Star Wars because of the scratch) and the copies play fine. And while the dvd's I was sent may have been totally blank front Taiyo Yuden or whatever, I copied them to store brand Sony. Plus the Star Wars disc still plays in the parts of the movie that aren't affected by the scratch.
The problem with the discs is the fuzzyness of the laserdisc playback which the official LFL release does away with. Additionally, the compression is very noticeable. And the bonus discs of other Star Wars specials could have used some basic level adjustment and if they were done today, would probably look clearer because of better digital compression since 5 years ago.
