the uk release only got a 2.0 since the uk did not have ac3 laserdiscs from what i've been told.
of course the japan release and the us release have the ac3 5.1 ntsc.
the last release being in japan in 2000 with burned in subtitles in the lower black bar area for the letterboxing.
this was missing the making of but added a behind the scenes look at episode II.
I only own the 1997 us set and do not have the ac3 equipment so it comes out of my tv downmixed into stereo.
i believe i read someplace that the g'kar pal set 5.1 was an upmix of the uk pal stereo mix? possibly taken from tv broadcast sources.
i probably should say european audio release since the g'kar was form germany right?
The TB set has a higher bitrate but i only own the g'kar since nobody i know has a set without crc errors. i've been able to circumvent this in the past on some of my burnt dvd fan discs in my collection with dvdfab dycrypter, but since i do not own the TB set i cannot try it out, LOL.
