Re: illicit viewers?
I have a 'SmartTV' with iPlayer. Generally the entire TV now crashes after watching one HD programme. Sometimes it crashes before watching any. That's when I have had to resort to watching iPlayer via XBMC.
Looks like they're determined to reduce the number of iPlayer users.
(Also, encrypting/protecting the feed, like encrypting the DVB-T2 version of the programme guide - I assume it's just a management "hack" because they were told not to DRM the video itself?)
