A network we have that gets funding through private organizations as well as some government funding airs the old eps of Dr. Who and the first season with the 9th Doctor. After the eps with the 9th doctor they show behind the scenes things about the eps.

And when I rented s3 the last disc was Doctor Who declassified with ten or fifteen minute behind the scenes for each ep.

If I were to rent Torchwood I would probably see the full length of what you get. We're probably getting snippets of Torchwood declassified during the eps.
