For those with an AppleTV, and those who just got the update with the KORTV channel. Is there any subscription from a cable provider required for that, or is that free to watch? Does anyone know what Korean channel programming is broadcast on that KORTV channel? Is it programming from channels like Arirang or MBC, or is it it's own programming? My mother in law is Korean and looking for ways to watch Korean TV programs here in the US. Her satellite provider (Dish Network) previously had a korean channel, but they just dropped it. Wondering if this could be a viable replacement?
