Hi,
The default TARGET parameter value has been changed from 75% to 95% 
between GDAL 1.7.3 and GDAL 1.8.
So please allways give the TARGET parameter when you make your tests, 
and use the same TARGET for all your tests.

It would be useful if you can make your test image available to 
everybody, so that people can compare their results with yours. If it is 
not possible, use a freely available image, such as NASA BlueMarble.

Could you also test on Linux 32 bits ?

Best regards,
