Brian, I had responded earlier but for some reason my email was rejected by list maybe because my official ID changed. In any case below is my response.
What version of gdal is this? KMLSUPEROVERLAY driver creates a hierarchy of regions that can be used to efficiently serve large set of imagery. As few points near higher resolution tiles are loaded. KMLSUPEROVERLAY driver generates kmz with this command: Gdal_translate.exe -of KMLSUPEROVERLAY c:\my.tif c:\myResult.kmz -co FORMAT=PNG I have not implemented read for KMLSUPEROVERLAY. Ogrinfo should be able to read kml but not gdal. Let me know if you have more questions. "v" gets appended for formats supporting virtual IO.

Reading images from knls are problematic at best. Can you give me some info on the stucture of the kmz's?
