The quality is shit not much better than the definitive collection laserdiscs, and those have the uncompressed full pcm sound.
Moth3r's transfer of the pal laserdiscs from 1995 are better by far.
It's funny to think a product released by lucasfilm in 2006 is not that much better than the asian bootlegs produced years ago. I have seen fan versions from these boards which either match the quality of the official release or beat them soundly in picture and sound quality.
Lucas should be severely criticized by the professional film community for this turd of a release, nothing short of a disgrace and a slap in the face to film fan's everywhere. But especially the true fans of the oot who made him rich beyond the dreams of avarice.
I bought my copies to review them, but I shall urge all true fans to not buy it. and in fact this release is so bad it makes you wish people had not caved and bought them because it should have been boycotted.
Also the 2004 release coupled with this of a new hope still has not been fixed, the sound problems are still there. Plus they still did not bother to fix the color correction and the garbage mattes around starships etc on all thee films.
