Wonder if the clip provided to Ofcom had de-interlaced stuttering?

If broadcasters supply material to Ofcom its supposed to be of broadcast quality. So (in theory) they shouldn't be able to send any old crap that looks like it was filmed on a potato.

Mind you Ofcom don't seem that fussed about "technical standards" these days, though in fairness some of it is probably beyond the broadcaster's control (perils of quantity over quality on Freeview for example).
