Some content is made lagally available for free in my country over video on demand systems like BBC iplayer or channel 4 on demand.
The BBC app does not all someone to download a programme to watch later over 3g. It does allow streaming. (And i don't know what they're using to detect 3g because you can download using a 3g dongle).
So, sometimes it's easier for me to just watch it on Youtube than it is to use the official app.
It is frustrating that I try to do the right thing and they prevent me, and do so for weird reasons.
