My Amarok is 1.4.7, was always able to play Shoutcast, although searching with it is a bit mindnumbing. I think, however, that many radios offer alternative ways of streaming than Shoutcast, it's matter of checking their websites (provided they have, like Digitally Imported Radio). And for TV, that one is more complicated, perhaps JustinTV? But it's not very legal I think.
