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.
Stratos is supposed to be going 16:9 on DTT, and yes they will be in SD.
If you want more HD channels talk to the broadcasters. Kordia ran the freeview|HD channel on 100 as a promo channel for the stores which is no longer required.
