As far as I'm aware the only stores that have any TV shows at all are the US and UK stores and the UK have very few. As for movies, pretty sure that's US only, the new rentals certainly are. What I know for sure is that there's no TV shows or movies at all on the Irish store.

To register on the US store you'd need a US credit card. Not something I have any way of getting my hands on at all unfortunately.
