Yeah, and Cinemax's channel guide marks titles with a "trueHDTV" logo to indicate that the program is available in HD (i.e. "BEDTIME STORIES FEATURE 03" on MoreMax HD doesn't have the TrueHDTV logo, suggesting it's SD up-convert). I know that HD transfers of both films exist, so it seems like maybe Dish is still working out some kinks—understandable with so many channels out today.
Films are natively HD. The question is, do they have an HD transfer.
Three Kings is older, wouldn't be surprised if they didn't have an HD transfer of it, but Pan's Labrynth just premiered, so surely they have it in HD. Maybe DISH had a technical problem and did an upconvert so they wouldn't mar their big day.
Yeah, the films in question are definitely available in HD, as Cinemax's website even acknowledges. Otherwise I wouldn't have brought it up.
And in the case of films, it's a matter of what's been transfered to HD, not what was made in HD. (Film is higher resolution than HD.) The reason I'm so excited about MGM-HD is to see new HD transfers of classics as they become available.
