its not being shown in HD on bbc or itv. in any case freeview cant handle HD resolutions at the moment, you would need sky at the least and sky dont have world cup coverage, now it might be shown on bbc or itv on sky, but we will wait and see
Only chance for world cup in HD for the UK (other than SKY) is to get an MPEG4 sat receiver and receive the german channels from Astra1. I would think that ARD and/or ZDF may show the odd game in HD as a public showcase.
Pace is having an MPEG4 receiver out but the one to have is apparently the dreambox 8000 (out early 06).
Premiere, the German equivalent of Sky will be showing every World Cup game in HD. They launch HD officially in Novemeber.
For those who don't know the Premiere range of channels are availible on Astra 19.2 deg, so all of you who still ave your old Sky analogue dish up, don't take it down yet, buy a Premiere box and enjoy.
