Would probably take more time to make the sub masters and duplicate from it than anything else, after all the BBC got burnt when they released a Dr Who video that had issues, so they had to change the way those were done.
Any details?
I know there was some degree of loathing of the BBC amongst Whovians in the 90s (can't be bothered to make it any more but happy to charge £100s for video releases each year), I can't imagine this incident helped.
I can understand that. In the days before content management systems the choice was modifying a couple of graphics files or editing hundreds of HTML pages
