Yes, I was originally alerted to this option by Vangelis when I was
having problems with looooong programmes, such as Wimbledon.
Also, if you specify the following command line:
get_iplayer "programme name" --option
you will get a list of the various options available. I forgot to say
that I check this switch before I go down the hslvhigh route. At least
the output alerts you to an HD version being available when you are
initially only able to download the SD option.

I'll try for you tomorrow if I get a chance.

It's encouraging that the bit rates for Radio 3 are pretty sensible,
recognising the content requires a decent rate to do it justice but it's
obvious here that they regard TV viewers as a different breed,
irrespective of the content! :-( It's interesting that DVB-T2 has
different bit rates, every medium seems to have its own standards. I
used to have a couple of Topfield 5800 receivers but they gave up the
ghost a few years back and from memory they only did SD anyway so these
days I use the Humax Foxsat-HDR.
