Like others, I have discovered this forum whilst trying to figure out what the BBC have been up to. Historically, I have used another Applian product, Jaksta to grab BBC radio shows.

Early on 06 January I simultaneously downloaded a handful of shows, one of which turned out to be incomplete. Later that morning I re-attempted the incomplete download, only to be hit with a message regarding secure streams. I was then only able to record the programme, and it was necessary to leave the iPlayer window open for this to occur. The change occurred somewhere around 9.30 AM GMT and it has remained in place ever since.

I have also stumbled across brief interludes when it suddenly becomes possible to download programmes once again, but these have been brief and erratic.

I suspect that those who report seeing incomplete downloads since the change, have done so because they closed the iPlayer window.
