Dorian / SPM:
Regarding the seg8 images take a look at this thead for how to use these files, or they can be used in DARTEL

Regarding the fiile selector, I think the bug you are referring to is waiting on the next update but if you want to fix it yourself here is what you need to do.
Change line 1325 in cfg_getfile.m (in the matlabbatch directory) to
case {'image'}, code = 1; ext = {'.*\.nii(,\d+)?$','.*\.img(,\d+)?$','.*\.NII(,\d+)?$','.*\.IMG(,\d+)?$'};
