Mark,

The JPEG2000 file was written with the JP2ECW driver but when writing
is complete it is reopened with the generic GDALOpen() which ends up using
the first registered JPEG2000 driver which turns out to be Kakadu.

I'm not sure if this is a serious warning.  You might want to try
generating your file with the extra option -co PROFILE=BASELINE_1 and
see if that helps.  I suspect that is similar to the Sprofile=1 Kakadu
option.  If the problem persists you might want to take it up on the
ECW SDK forums at ermapper.com.

Best regards,
