I am glad that PTViewer does not show a worse image than QuickTime. In
reality it shows a slightly better image than QT, but it is difficult to
see the difference with such a panorama. That pano lacks the fine
details and textures where ptviewer shows a clearly better quality.
For an image that really shows the difference you can go to the PTGui
gallery:
http://www.ptgui.com/gallery/
and look at the "Paraglider" pano. It is near the end of list. Look left
and up at the back of the wing ad see the artifacts caused by the
viewer. Pan slowly. Try zooming in and out to see what happens. Compare
the two viewers at the same zoom level (the default zoom is different).
