Oh sorry, I guess you mixed up my questions.  I know what projection the
NASA's Landsat WMS layer is in, I just don't know how to get the wmsplugin
talking to "Tiled WMS" (http://onearth.jpl.nasa.gov/tiled.html).

Apparently you can get some infos about how to access it by sending a
GetTileService query, but that's all they're sending back:

<?xml version='1.0' encoding="UTF-8" standalone="no" ?>
<!DOCTYPE ServiceExceptionReport SYSTEM "http://www.digitalearth.gov/wmt/xml/exception_1_1_0.dtd ">
<ServiceExceptionReport version="1.1.0">
 <ServiceException>
   Service denied due to system overload. Please try again later.
 </ServiceException>
</ServiceExceptionReport>

  Gabriel.
