Well GordonSBuck had it - I needed to set raw in function settings. As far as I'm aware there is no mention of this in the manual (though I may be wrong I haven't read it cover to cover) why is there a need to set it in both locations without a warning - I'm really disappointed that it was so easy to get this wrong and that, as far as I can tell, this wasn't something I was able to be aware of unless I was able to download the files to a computer. I am pretty careful so this sucks ! OK sulk over - i still love the camera, just an expensive trip wasted - apart from the food and beer and the beach and the sun and the diving and the good days out and the pretty girls and the wine and the markets !
To be more precise: both settings do not depend directly on each other, so i would not blame Canon... 
Settings - RAW configures if you want to shoot RAW instead of JPEG.
Menu - RAW+JPEG configures to create an additional JPEG to a RAW picture IF "Settings RAW" is active.
What do we need the later for? E.g. for direct printing out of the camera, that's not possible with RAW only. Any picture post processing (red eye, ...) isn't possible too, so this option does make sense for me.
And, yes, this is explained in the manual, but as far as i own the german version, posting the page number might not be helpfull.
Like many other, i needed to make this mistake to understand the point. It's "learning by doing" i think and you've made the right conclusion to remeber the good sights of your trip...
