[Gvsig_usuarios] problemas al añadir raster

Hola,
quiero hacer una consulta porque estoy teniendo problemas a la hora de
importar un raster en gvsig.
La versión que uso es la 1.11.0, sobre windows XP, si bien cuando
intento cargar la misma imagen usando gvsig 1.11.0 sobre ubuntu obtengo
una ventana de "error en la carga de la capa".
El problema es que la imagen que se muestra en la capa (añadir capa ->
archivo -> añadir -> Archivo de tipo gvsig Raster Driver), presenta
alteraciones respecto a la imagen que se debiera mostrar. Aparece como
si estuviera pixelada y con colores...
Mi intención es aplicar diferentes cálculos y ratios entre las bandas de
la imagen mediante SEXTANTE, pero por el momento me es imposible
trabajar sobre ésta. Me gustaría saber si hay algún modo de modificar
las opciones por las que se carga el raster, de modo que pueda
ajustarlas a las especificaciones de mi archivo.
El archivo es un img, con formato PDS, con 5 bandas.
Os adjunto la cabecera de la imagen que intento cargar, por si a alguien
le da alguna pista.
Muchas gracias!
