I don't know about chromecast but my son bought me an android box off ebay a short while ago for I think about £55.00. This works through my broadband on the TV (which must have an HDMI connection) and through it you can access Modbro which has loads of films, sports channels and podcasts all for free. It also has XMBC which has loads of free films and also TV series, mainly US ones, I am currently catching up on Breaking Bad as it has all 7 series available. The only downside is that it is quite slow to load and there are occasional duff channels so you have to be a bit patient when loading stuff. I hope this is helpful.Incidentally my son said there were a load of porn channels on it at first which he removed before giving it to me.
