Almudena,
I tried this with the FWTools linux version of mapserver and
was able to render it fine. However, loading and browsing
the file in OpenEV resulted in a crash in the ECW library
after a partial load.
I tried rendering it with the FWTools windows version with
no problem. Loading and browsing in OpenEV also worked
fine.
I presume you are using binaries from DM Solutions? It may
be that they need to upgrade to more recent ECW (and/or GDAL?)
libraries to get around this problem. I'm sorry I can't provide
anything more concrete.
Best regards,
