Like most plasmas the Panasonic TH-42 PH9 only has a native resolution of 1024x768 (a 4x3 res requiring some odd stretching for Widescreen).
This is much closer to the 960x576 (Widescreen Anamorphic PAL) coming out of a decent de-interlacing DVD player than the 1920x1080 that the HD-DVD disks are encoded in or the 1280x720 (composite) 1366x768 (VGA native) that the XBOX 360 will be outputting to most LCD screens.
Hardly surprising that there is not much difference between DVD and HD-DVD on most Plasma.
As far as I know no plasmas actually have a proper widescreen pixel format other than the very latest (and largest) 1080p native models.
