The UK versions have scenes not on NBC, and vice versa. From the rough cut, they made a UK cut and a US cut. The new blu-rays are taken from the U.S. cut. Everything from the NBC versions is on the new blu-rays because they are using the actual elements that were broadcast...that's why there are bits on the UK cuts (some used for the old dvds) that aren't on the new blus. I am thrilled with them, as is the surviving cast. Melissa Gilbert released a statement about them this week.
Why would they have prepared alternate versions for the UK ?
No other show did that .
In the unlikely event they actually did the likelihood that those versions would have been used for modern dvd's is remote.
Are you confusing Uncut and Syndicated for UK and US?
The only difference between a UK broadcast of an old US show and a US broadcast would be that the UK always showed the original unedited network version whereas the US suffered edits once the series went into syndication.
So while the UK discs should feature the unedited episodes unlike the Imavision discs the Blurays are being restored to the original broadcast length so there should be no footage in the UK set not on the Blu.
When the show first aired in the UK the BBC screened the first season but presumably it didn't do well enough as they didn't buy any more seasons.
It was left to ITV who did what they did with most US series at the time . They used it as filler and it was aired by each regional ITV station ( 13 of them) in their own slots on different days at different times often months and sometimes years apart. Many regions never even got close to the final season and I don't think any showed the whole lot. Most aired it as daytime kids show.
First proper UK run was from C4 around 1992.
But the UK situation is irrelevant regarding Remember Me Part 1.
If you actually look at the ending as it appears on the Bluray its quite obviously not something that would be broadcast .
The syndicated versions would often have additonal captions similar to the one on Remember Me Part 1 as it appears on the UK dvd where features were split in 2 but even on the dreadful Imavision discs none feature an edit as glaringly bad as the Bluray of Remember Me Part 1.
They do feature video generated captions and in the wrong places on at least one (Gold Country IIRC) but none look as bad as the Blu.
To be honest I think your theory about alternate UK versions is incorrect although I'm willing to change my mind if you can tell me of any scenes that are on the UK dvd's that are not on the Blurays .
My belief is that Imavision got stuck with syndicated versions of old broadcast prints that had been cut by tv stations while the European dvd's are the correct uncut versions that are basically the same as the Blurays .
The bodge up on Remember Me could support your theory that it was intended to be a feature which is why no caption was available for the Blu version of Part 1 but they really should have opted to edit in a caption from a version with a proper ending instead of what they did.
I'm sure Melissa Gilbert is thrilled with the Blurays as they do look better than we've ever seen the show before .
There's not really anything to dislike - but shortcomings should be mentioned .
