How do I move from 'subtitle-supported' listening to actually catching Xhosa in native content?

I’ve reached an intermediate level where I can read basic Xhosa, but whenever I try to watch local South African shows, the speed of the speech combined with the dense agglutinative structure makes me feel like I’m back at square one. I’m trying to use Chickytutor.com to break down fast-paced audio clips I find, but I’m struggling to catch the 'glue' between words. Any advice on ear training?
