FWIW, I was able to download this clip with a very small patch to get_iplayer. AFAICT, the access token for this clip is ultimately returned with "auth=" already prepended, which get_iplayer doesn't expect and thus duplicates, giving a bogus query string for the rtmp URL. This appears to be peculiar to Akamai CDN connections, but not necessarily all of them. As Nigel Taylor pointed out earlier, this isn't related to iPlayer content per se, but a workaround seemed benign enough that I could roll it into my get_iplayer fork. Hope I don't eat those words.
Patch is attached. Info on my fork here: https://github.com/dinkypumpkin/get_iplayer/wiki/instructions
