What you have to remember is that it didn't look that bad when it happened. TVs are a lot less sensitive to breaks in sync than video recorders are.... hence they look a lot worse on clips on the internet.
By the time ITV went 24 hour it was happening 15 times a week, as the same procedure was used for TVam. Although that's still only once more than the rest of the country so hardly worth it. The glitch was also seen on Channel 4 which would complicated it even more
Did they ever fix that awful cut / picture roll from Thames to Lwt that you see on the earlier clips?

It would have been virtually impossible to have removed it, unless LWT were to have genlocked themselves to Thames, then applied the relevant delay to compensate for the timing difference as seen at the BT Tower between the two incoming sources.
The only other way would have been for BT to have had two frame syncs at the Tower, such devices didn't even exist until the late 70s, and who'd have paid for something only to used once a week anyway !?
