It does work, it is just slow as hell. Non-interleaved is not suitable for
streaming since audio and video are at different places so you have to do a lot
of seeking. Since most ISP use gigantic queues and caches, seeking simply is
much too slow. Using a really big cache might help, but then you might just as
well download it first...
