I backed up Superman Returns HD DVD to my hard drive. It plays back fine with powerdvd ultra 7.3 except I can't turn off the subtitles. I can only switch between english, french, or spanish. I have backed up several other HD DVD movies with no such problems with the subtitles. Does anyone know how I can turn off subtitles or remove them? Also, not a big deal, but I have no menus on my backup of superman returns. I did not check the box for "Remove all menus from HD DVD". Any ideas?
