I see that Freeview have added Stratos to channel 100 replacing the HD Demo channel.  

A friend of mine said he read that they [Sky i believe] weren't rolling out any new HD channels in the short term as they could get 4 SD channels over the air or 1 HD. 
Who was sending out the HD Demo channel and why can this not be used for a better quality HD channel.
Stratos quality is pretty poor [with a skewed ratio] although it was nice to see some in depth news about the rest of the world on the Australian News hour.
