The best SE Trilogy set is the GKar version which is a German DVB recording and has a German crawl and subtitles.
Following that in an all English format is the TB Release which is a Scandanavian DVB recording. This set has an on-screen graphic in the top right corner.
Both are PAL.
I am sure that the talented ones out there could take these two sets to make one perfect version, preferably in NTSC so that the films run at the correct speed and are the correct length.
I had never noticed the PAL 4% speed-up before until it was mentioned here but now I am buying all my fave films again in R1 NTSC so that they run correctly.
