Comment (by ersts):

 Replying to [comment:27 Coatman]:
 > Please remember that the first several versions of GDAL that were
 released, properly displayed JPEG2000 images under Mac OS X, using BOTH
 Jasper and Kakadu.

 As I have noted in previous posts, displaying JPEG2000 images in QGIS on
 Ubuntu versions <= 8.04 (with jasper) work just fine, while other
 platforms it did not. As of Ubuntu 8.10 that is not longer the case. So
 now, the JPEG2000 display errors are present on all platforms, but is not
 specific to QGIS ( you will also experience these display issues in
 FWTools [compiled with kakadu] or with gdal_translate [native 8.10
 compiled with jasper]). Thus the problem has to do with, or a combination
 of, libjpeg, jasper and/or kakadu, and GDAL.

 > There seems to be a strong bias here (that I do not understand) against
 Kakadu

 That is simply not the case, it is a broader issues that has been
 documented with other libs several times in this and related posts.

 > Please understand that I am trying to help, and just ask that a
 functionality that was in the first version of GDAL be restored to the
 current version.  I am not requesting a new feature that has never been
 used.

 Your interest is acknowledged but your passion maybe misdirected and
 misunderstood. The QGIS raster capabilities are tightly wrapped around
 GDAL which itself relies on numerous other libraries. While we all want
 the best app possible, many folks contribute only as volunteers and each
 QGIS dependency has numerous outstanding bugs themselves; the ones which
 are most important to us individually ultimately seem to be the ones take
 the longest to fix.

 I am sure in spirit of the open-source paradigm we can all contribute
 toward the golden goal and I openly ask for any patches and ideas folks
 may have that may bring a conclusion to this problem.

 cheers.
