[mapguide-users] Some tiffs work and others don't - does anybody know why?

If you are using GDAL, the debugging trick explained here, should at 
least give you a hint:
http://trac.osgeo.org/fdo/wiki/FdoGdalNotes#DebuggingRastersinMapGuide

You can also try the GDalInfo tool, and examine the tiffs for differences:
http://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries

FWTools is the full package, not sure what minimal packages that have 
GdalInfo.
