Just ordered Cinemax on line to check it out,while it says that it is HD it does not seem to be the PQ of the channels on the HD pak.The PQ is far better than SD channels,but still seems to lack the crispness of HBO-HD or for that matter HDNET(but other than Discovery-HD not much compares to HDNET)It still is HD though and from what the CSR was saying if something was on Stars that could be broadcast in HD,and although it is not listed as a HD channel it will be broadcast in HD,maybe this is the first steps of D* playing around with the new birds.
No flames please just passing on what I have heard and seen
