If the show you missed is on netflix then... yes, I'd imagine it'd be quite possible. :P
I can steam netflix, but is it possible to steam my TV show I missed through my wii?
netflix doesn't have recent episodes - they are best found on hulu, but i am sure you can find them other places, I'm wondering where?
Ah, ok. That's more clear of a question.
Unfortunately, the Wii's browser "Opera" isn't very compatible with most streaming websites. Youtube is the most well known one, but you won't be finding any TV shows there. I'm not entirely sure what other streaming websites are compatible with the Wii. Some other members would probably know, though.
