White Knight - Id suggest getting a refund based on the fact you were missold at POS - that TV appears never to have been "HD ready" (only capable of high definition which doesnt technically make it "HD ready") and therefore isnt fit for use as per advertised, as its likely that only a few channels wont be HDCP encrypted (even 'free to airs' might be depending on the carrier) once HDTV is established...
Definitely worth chasing this with whoever sold it to you and the manufacturer - looking at the
EICTA site (which defines the HDTV standard in Europe and advises as a minimum a "HD Ready" TV requires HDCP over DVI/HDMI) it conflicts with the information on this website regarding your TV:

I would also check to see if Sky/Cable/... have now confirmed how they are to transmit HDTV with HDCP encryption - it looks like that
Sky are expecting at least a "HD Ready" logoed TV with their new HD boxes which ergo your TV isnt and so will get limited support (unlikely youll get any premium channels without HDCP) initially which will get worse as the standard becomes established...
Im unsure if you will get a full refund, but if I was in your position I would pursue this - hopefully the info above will be of some help...
P.S. It does look like that your TV was introduced before the "HD Ready" label was standardised (c. Jan 2005), but as it was labelled with the "HD Ready logo" which is provided via self-certification, it is either mis-advertising on behalf of the manufacturer or the retailer - its irrelevant that the standard was defined after the TV was produced since it was 'certified' and therefore a normal consumer would naturally assume it would meet the minimum requirements for "HD Ready" TVs...
