(Almost) Admiring Miro
I'm not a big fan of IP TV. After all, the Net is essentially everything TV isn't - interactive, non-linear, intelligent (well, some of it). But if you really must watch TV-like things online, the best thing to do is to check out Miro - the new name for Democracy Player (which always struck me as misleading). Speaking as a non-connoisseur of these things, it seems to do everything it should, it looks pretty cool - and it's free software. But only if you absolutely must.
