Doctor Who competition

CBBC, the BBC Children's channel is running a Doctor Who competition. The main prize is the first season DVD Box Set, a sonic screwdriver with psychic paper and a TARDIS mobile phone flasher. Cool.

Two catches.
One,CBBC is a digital only channel and you have to enter the competition through it's interactive service (aka "the red button").
Two ,presumably you have to be a child?! So either masquerade as a small person or persuade your closest child relative to enter for you.

The interactive service will also be showing some clips from the DVD, including some of the special features. That's pretty cool, the "special features" section of the TV channel promoting special features of the DVD. So much content and so many distribution channels....
