I know this was reported on the mailing list and has been fixed for the next release on github, but on https://github.com/get-iplayer/get_iplayer/issues/157 it says you can't use to get the programme to download.

I've tried this with Peter Grimes and using did start the download successfully.

I doesn't work if recording from a search (), which might be the case for a pvr job. The suggested form works in all cases. I've amended the issue description.
