This is true, but even the quality of the audio is off. Like they're only using the camera mics... I'm not sure what's going on with it.
The posted videos look like they're VHS dubs, indeed one of the comments on the video suggests the uploader "acquired" these back in 1987 and they've been halfway across the world twice over in the meantime.
VHS in my experience was never very good at the audio side of things and I would hope the (presumably) Betamax masters sitting on a shelf somewhere at Leeds are better quality both audio and visual wise, even if all they are good for as far as ITV are concerned gathering dust.
