I was looking at my collection. I have the Fleischer series on 2 disc. The discs come from Platinum Disc Corporation, and they were released in 2004.
There are lots of problems with this release.
1) The audio was "digitally enhanced" in 5.1. Bleecccchh!!!
2) The distributor's logo will appear in the bottom right corner for a few seconds during each episode, like you see with TV station logo's.
3) The picture looks pretty soft.
From davextreme's posts, heseems to be working on looks and sounds like it will be far superior to what I have.
