The German SDTV SE transfers are really our best hope for some scenes. Even when grabbing off the best laserdiscs with the best players in the world, because of the letterbox format, you are only getting around 270-300 lines (or much less) of resolution compared to the anamorphic lucas DVDs at 480 - 576 lines.
So even if the laserdiscs where a perfect transfer of the original film (which they're not) the quality level is still a lot lower - more so when you look at the other limitations of the laserdisc format.

If anyone can point me at SDTV version of ESB and ROTJ I would be forever in their debt...
