[TIGHazard]

Quite possibly. When I watched one of the editions on demand earlier in the week (Wednesday I think) it began with a few seconds of the coming up slide from the Red Button, so a dirty copy from what was shown live was uploaded. 

Saying that, that happens quite frequently across iPlayer - I watched a classic comedy a few weeks ago that had the BBC Four DOG in the corner and the BBC Four CA over the credits, when obviously a clean version exists in the BBC.

I don't think Steve Williams is on this forum (sorry if you are Steve!) but over on the previous places he's mentioned before that there are multiple routes to the iPlayer. But also metadata handling can be an issue, so a clean version of something can be uploaded, get stuck, and then iPlayer effectively has to treat it as a live programme.

Surely though Today at Wimbledon should be able to go directly to the iPlayer if the OB can put the direct court feeds on there!
