I think you've answered your own question there - indeed with the limited channels of the time there was probably even more crititicism of repeats than there is now.

There were other options than skipping or repeating episodes to align them - especially with Prisoner Cell Block H airing overnight you'd think it would have been easy enough to double them up until they caught up.

Blockbusters in daytime probably more trickier but I don't think it was ever networked and different regions would air it anything from once a week to 5 nights a week. Not sure what Yorkshire/Tyne Tees did but possibly dropping one a week on one and adding one a week to the other until they were in sync could have been an option, but they had other programming commitments to think about too and fixing one issue would probably have caused others.
