Head of BBC HD Danielle Nagler has posted a beginner's guide to HD service over on the BBC TV Blog: How to get the best out of HD TV. Needless to say satellite viewers suffering with substandard HD transmissions are commenting in force as there appears to be little improvement with the great encoder/bitrate quality debacle for non-Virgin viewers.
(Incidentally, has anyone experienced Freeview HD yet? How does it compare with Virgin and Sky? Just interested).
