Shaun,

I don't suppose you can make a reasonably sized file available that
demonstrates this problem?

My first suggestion would be to disable the JP2KAK driver, and see if
another JPEG2000 driver (ECW or MRSID based) does better.

eg.

export GDAL_SKIP=JP2KAK
gdal_translate -of hfa -srcwin 0 0 100 100 North_Queensland_25x.jp2

I'm not really aware of a mechanism to open files "non-seeking"
with Kakadu.

Best regards,
