[James2001]

UKTV Play runs at 25p (so everything's like it on there regardless of how it goes out on air), unless you're downloading on a Sky box (where it's 50i), but I'm talking about the actual broadcast channels, not UKTV play (sorry if that wasn't clarified!).

Several shows have been affected by this, off the top of my head, in addition to The Upper Hand there's EastEnders (which was the first show to be affected, back in November/December), Casualty, Some Mothers Do 'Ave Em, Whatever Happened To The Likely Lads, Howard's Way and When The Boat Comes In. Possibly on other shows I haven't noticed (or ones shot on film or with a film look where it would only really be noticable if the show has quickly scrolling end credits).

Looking on UKTV Play I notice every episode of The Bill from mid-2001 until the last episode in 2010 is on there, I'm guessing they've been there for a while, ingested into their systems before this problem arose, and that's likely why the Drama screenings aren't being affected even though they're "new" copies (previous repeats were in 4:3 with the 2003 Fremantle ident at the end, this is the first time UKTV's shown them in 16:9, with the 2018 Fremantle ident at the end).

If you're going to check out how it looks on TV, best to be sure you don't have any sort of motion interpolation turned on on your TV, as that will affect things.
