Ryan,
You're posting in the HDTV section of the site, so I'll presume (perhaps erroneously) that you're interested in HDTV. You should be able to get terrestrial and/or satellite HDTV from the Korean broadcasters. For a bit more money, you may well be able to get HDTV from Japan. Japan has a satellite-based HDTV service called BS (no kidding, that's what it's called. I don't know what the letters stand for.).
The cool thing about Japan's HDTV satellite broadcasts is that most of the movies are in English with Japanese subtitles. You should be able to get movies in HD that aren't available in the US. These are often movies that aren't available in the US in HD. Pretty cool if high quality movies are what you want. Unfortunately, if you want DirecTV for the football or basketball packages, I don't know if we can help you. The Korean peninsula is way outside of the area of coverage for the US geostationary orbit slots that DirecTV and Dish Network own. Way. I think the Japanese stations might carry some Seattle Mariners and New York Yankees baseball games due to the prominent Japanese players who now play for these American teams. Nonetheless, I don't think you'll get the full DirecTV Sunday Ticket any time soon in Korea.
There is a Korean HD enthusiast who posts from time to time on AVS Forum. I really wish I could remember his name. Do a search on this forum and you'll learn a little bit about the feasibility of getting Japanese BS broadcasts in Korea.
Welcome to AVS Forum and have a great time in your assignment/job in Korea. Hope we can be of help!
