TV or not TV

Anyone able to tell me what would be a good start for KOREAN dramas or films? (In Korean with subtitles, of course.) I remember someone told me about a site with series, because I'd also like to get known to some Spanish series , again, with subtitles. And if by chance anyone happens to know where to turn for series in Arabian (standard) with subtitles... but hey, that might be asking too much, right?
