Has anyone had any download issues with the Watchdog Episode dated 29/3/2012, because I've been trying to download the episode, but it says "Download Unavailable"?

Unavailable to download for me too.

"This episode is not available for download. To find out why, please click here."

I had the same message on my LG TV a few days ago for an episode of Doctors on iplayer, next day though it was available with no problems

Try Youtube... you will be amazed at what is avaliable on there and not yet available anywhere else....
