could i have little help with get-iplayer?

I'd really like to be able to download programs to my phone and watch them with my desired player therefore being able to seek much easier than i can in a brower window. i have get-player through debian chroot, typed in get-iplayer and get a big list of progs. i am specifically after the last episode of dr who which is on the website but not in the list that get-player shows. i also went to the get-ilpayer page and found the prog index is 774 but typing get-player 774 in chroot return an error 'unmatched programme index'

help please!!!
