Yet, you had been made aware of those changes 
in a verbose manner with my post of  Aug 3rd: 

http://lists.infradead.org/pipermail/get_iplayer/2016-August/009353.html

In GiP 2.95 (release), the hls tvmodes are the default; 
not specifying a tvmode or setting --tvmode=best 
means that GiP will exhaust all hls modes (from higher 
to lower quality) until it finds the best available one.

If you want the best available among the hvf tvmodes, 
then set --tvmode=hvfbest
Likewise, use --tvmode=flashbest.

If hvfhd isn't available (720p50fps), it's a good bet that 
neither hlshd nor flashhd (both 720p25fps) are; I would try 
myself --tvmode=hvfbest to fetch either hvfsd (540p50fps) 
- if available - or hvfvhigh (540p25fps); both flashvhigh/
hlsvhigh (468p25fps), which are the next step down from missing 
flashhd/hlshd, are slightly inferior to hvfvhigh...

But again, 95% of the answers to your queries 
here in the list are found in the detailed FAQs/
Release Notes that dinkypumpkin painstakingly 
compiled:
