Just came across this.. don't know much about it.. maybe one of our buddies across the pond will know more.
Doctor Who - Dreamland Trailer (http://www.youtube.com/watch?v=WpTpBOIBAEU#)
Brothers Meds & Feathers should be able to elaborate! :)
Yeah this is a small animated episode that is on our freeview station. You press the red button on your remote control and it pops up for free. Started on Saturday, set in Roswell. The animation is pretty shocking ;)
Episodes are also available on the web once they have aired via Sky or Freeview.
Looking now www.bbc.co.uk/doctorwho (http://www.bbc.co.uk/doctorwho) has it up but I don't know whether there is any region locking involved. I can't watch the episodes at work (which uses French IP addresses) so there may well be.
I'd heard the animation was...interesting but I haven't checked any of them out yet.
