Thanks. Wasn't aware so will do that and try to get a freeview box off trademe. I noted that hd freeview is only available on UHF. So that dish on the roof is going to be a display unit only over the next few months :-)
You can buy a sat box and plug it in to your sky dish and receive freeview channels, the signal comes from the same satallite...but freeview (DVB-S) is only SD not High Def. If you want High Def, then a DVB-T box is required and a UHF aerial pointed to your local transmitter. Not all channels are HD either and not all the programming on HD channels are HD.
