Generally the highest rez material we see today is the video from HD cameras. I beleive those generally will go out to about 1400 lines of horizontal resolution. As far as HD DVD and Blu Ray, it was my impression that even those will not be in the 1920 rez category and probably more akin to D-Theater.....but I could be wrong.
All the testing that we have done with DVD Forum on HD-DVD have been at 1080p so the encoding will certainly be at 1920 lines. However, this does not say that the telecine transfer had that resolution. Clearly for computer generated content such as Shrek, one can expect the full resolution out of BD (blu-ray) or HD-DVD formats. And over time, telecine equipment will no doubt improve to produce closer to the full resolution of the formats.
Here is another consideration. With HD content encoded
in 1080, staying in that resolution all the way to the display will mean better images even if the content doesn't have as much resolution. By avoiding a downsample in the display to lower resolution, one avoids the artifacts introduced in that step.
