Thanks spalife, I'll check the setup when I get home later. The odd thing is that the setup instructions use wget and they worked up until the point I got stuck.
Also, is there a way to block https ads like those on youtube on the Chromecast? I'll be happy to pay to get rid of them when I have the opportunity, but that facility is not available in the UK yet.
It can be done but it requires a bit of technical savvy and patience.
