I wouldn't expect Chiller in HD, at least at first. Maybe once DirecTV has FINALLY reached that point of capacity they've been bragging about for who knows how long. LOL Chiller itself should appear on March 1st, and I'm guessing on a low channel number.
D* could decide to not let anyone know about anything and just dump it on you when it happens.
Rememer you are in the minority here, 99% of the subs have NO IDEA what D* is doing or do they care, as long as thier TV works when they turn it on.
relax, the channels will come in due time, nothing will happen till at least the 1stof the two sats are up and been tested and operational.
As for where Chiller will be, no one knows at this time, but I would guess it would be somewhere from 201-325.
Someone asked about what programming will be on what sats, that is at D*'s discression, they can move channels from one sat to another as they need.
