I'm finding that my Tru profiles are also not acting the way I originally designed them for, and I'm currently updating them. I have a sneaking suspicion things changed after firmware 1.0.7.1.00 was installed on my camera during it's last service.
If you do, could you post a listing of the actual settings in addition to the Profile files for us C100 users? I can e-mail you a document that you can just fill in if you'd like instead of having to write it all out.
