Hi Tony - thanks for your interest.
This is where I look a bit of a nonce! Out of deperation I've taken my tuner card out, rebooted and reinstalled it and rebooted again it and its now sending me through the options for satellite, cable etc... which it wasn't previously - I PROMISE!!!!
I've now got a Sky feed being received through Composite1. However its not letting me past the IR blaster checks now, so I'm off to search for a hack or workaround to this.
Thanks anyway - they way it's going I'm likely to be posting other silly questions on here as I muddle my way through getting things up and running.
Cheers,
Christoff
