Hi,

Are you sure the -b stuff is working in 1.1.8?  It might just be ignoring it and
copying all bands.

Well, there have been lots of changes - significant and otherwise since 1.1.8.
I think you will need to debug your problem or provide something simple I can
use to reproduce your problem if you would like help with it.  I can't imagine
there is any fundamental reason you can't use 1.2.1.
