I'm confused. 

Using the old version ffmpeg, don't you get good output irrespective of this change at the BBC?

Because in that case, surely the solution is to take this to the ffmpeg devs, tell them about the change that's causing ffmpeg to fail to identify the brainfart problem, and get them to fix it in future builds.

We can easily fix ffmpeg (even if it means patching it ourselves), but we cannot in any useful way influence the BBC's encoding.
