Discrepancy between iplayer & get_iplayer

[Expert Geeks]

Hi All,

I'm having an odd issue where downloading the Select Committee of the 
'Conduct of Boris Johnson' is a file of 58 minutes regardless of the 
quality (hd, sd & web tried). The file downloaded is always 670mb (or 
thereabouts) so the quality seems to be being ignored.

The file is also the same regardless of the method, --pid m001krfw or 
searching by name, whereas the version on the iplayer in the browser is 
the full 170 minutes.

You may question the sanity of someone that wants to watch 58 minutes of 
blather and bluster, let alone 170 minutes.. but I'm curious why the 
disparity and whether it's possible to get the full version.
