Same setup as Greg (my binaries), takes a few minutes to open.
A thought - gdalinfo on the jp2 tiles uses the ECW JP2 driver, which is a
plugin on the Mac, but I wonder if the vrt is ignoring plugins and using the
builtin jasper driver (slow).

Thanks, Tom. Now that I am back on my machine, I see that it is all raster
layers for me as well. This is also trunk from several hours ago.

My GDAL gdalinfo uses the hardware accelerated Kakadu based JPEG2000 code,
which is up to 10 times faster than the software based Jasper based JPEG2000
code. So, why then does it take me with the faster GDAL Kakadu JPEG2000 the
same time, several minutes, it takes William with the slower GDAL Ja
I said that I disabled the ECW JP2 plugin and it took *longer* than my previous
test. That is, using the Jasper driver takes much longer than the 3-5 min with
ECW (for me) or Kakadu (for you).

Giovanni, Is this what you are experiencing? When the .qgs project file opens
for you in a few seconds, rather than in a few minutes, as reported by Tom
Elwertowski and John Tull, are the raster layers invisible? Greg

Will fix that today.

yes, no problem
Ok, r12815 contains a fix for the multiband display problem. The rasters
display for me now.
But, using JasPer for jpeg2000, I got the segfault now that was reported by
others if I zoom in a few times.

Thanks. Aaaddd, it looks like it fixed the speed problem opening Greg's
sample project!
But, sorry Greg, I don't know when the next release will be to have this fix.

I can confirm that the trunk build loads both project files in several seconds
each, and all rasters are being displayed. It looks like the $1000 reward you
offered should go to Marco.
Cheers,

I am pleased to learn that there may be a fix for the long-standing,
show-stopping Qgis slow startup and JPEG2000 problems. Unfortunately, it
appears that this fix will not be available on http://www.kyngchaos.com for Mac
OS X Qgis users until after version 1.5 is officially released, perhaps 6
