TIFF can only work on Mac OS X with the xdv2pdf driver; it is not  
supported through xdvipdfmx (on any platform). So the results will  
depend which driver you're using.

IIRC, there's an issue in xetex 0.996 (TeX Live release) and the  
accompanying xdvipdfmx, where JPEG files are scaled incorrectly if  
they have EXIF resolution data (e.g., from many modern cameras)  
instead of the older JFIF file format standard. I think this is  
corrected in the latest sources.

It depends which platform you're running on. XeTeX on OS X accepts  
whatever QuickTime accepts (practically everything!) at the  
typesetting stage, but on other platforms it only knows the same  
formats as xdvipdfmx.

With the move to xdvipdfmx as default driver (even on OS X), maybe we  
should remove the QuickTime-only formats from xetex.def, so that  
xelatex won't even try to use those (unless the user does something  
to explicitly enable them).

Different in what way? I hadn't heard of that.
