Peter,

Does "gdalinfo --format mrsid" report some information indicating
the driver is available?  Does gdalinfo on the file in question
work?

What version of MS4W are you using?  I hadn't realized a new
one with GDAL 1.3.0 had been released.  If you are using an 
MS4W with GDAL 1.2.6 or earlier, then you cannot just replace
the GDAL DLL with a new 1.3.0 one and have it work.  

Best regards,
