Ok, I’ve checked a couple different pressings of the DC laserdiscs to see how they compare.

The repeated line occurs in ROTJ, first during Chapter 24 of Side 4 and again, with some other unique dialog preceding it, during Chapter 13 of side 5.
Results:

1st US Pressing:

Has commentary at both Side4/Ch. 24 and Side 5/Ch. 13 as presented in Harmy’s despecialized. The second half of the Side 5/Ch. 13 comments are repeated from Side 4/Ch. 24.

2nd US Pressing:

Has dialog only on Side 4/Ch. 24. The Comments during Side 5/Ch. 13 have been removed entirely, even the first half which was unique.

1st and 2nd Japan Pressings:

Has dialog as with both US pressings on Side 4/ Ch. 24. Comments on Side 5/Ch. 13 only include the first half of the comments as they appear on the 1st US pressing, meaning all comments are included and nothing is repeated.

To me the ideal way to present this would be as it appears on the Japanese discs. Does anyone have an opinion or comment on this? I guess I could just post both versions and people could decide which they prefer. 😃 I’m going to re-edit ROTJ before posting all three upgraded commentary tracks.
