Sorry about the slew of apple stuff, but this is more for me to check when I get home. Seems there are some Free iTunes HD TV shows up on iTunes. Seems (according to the comments) they aren't available in Canada. *sigh* Sucks to live in the north it seems. Hopefully this link willl help my 'merkin friends though.
However, these two links claim to get itunes downloads from anywhere, though it's legality and tested-ness is unknown.
