Yes, KBS World can be seen outside Korea through satellite, but I'm pretty sure you have to subscribe and pay a monthly fee. Check their website for further info.
Now as for streaming sites, that's another thing entirely. I came here looking for URLs myself. For some reason, after I updated my KMPlayer, all the k-tv channels urls weren't there anymore. I used to check MBC every now and then and now I can't. *pouts* Ah well. Actually, if you guys have a list of mms and urls to use, that'd be awesome.
Re: mysoju and crunchyroll. Whilst they're certainly a great resource for newbies who don't know where to look for dramas and movies, they're not exactly great for a)video/audio quality and b)all the fansubbers who spend hours and hours fansubbing stuff only to be completely disregarded by uploaders who don't respect the fansubbers' policy (all the fansub groups I know and that make high-quality subs don't like streaming sites for exactly that reason). Me? I prefer getting the raws and then check the official fansubbers' page or d-addicts to get the subs. The only streaming site like mysoju I'd trust is dramafever.net. Just my 2 cents.
