utgg,
Just thought I would mention that get_iplayer 2.9.1 seems to be able to
deal with on-demand HLS streams by using ffmpeg.
I've been having a play with it to see what happens and thought I would
post an example in the unlikely event that it might help.
It is using the ffmpeg.exe (2.2.3) that I had previously downloaded to
my Windows machine.
get-iplayer couldn't find an on-demand HLS 320kbps version of the PID so
the following is for the HLS 128kbps.
This is the cmd window text:
