The document returned by http://www2.terriscope.fr/geocache/tms/1.0.0/osm@WGS84 contains <TileSet href="http://www2.terriscope.fr/geocache/tms/1.0.0/osm@EPSG:4326/0&quot; units-per-pixel="1.406250" order="0"/>

But the URL http://www2.terriscope.fr/geocache/tms/1.0.0/osm@EPSG:4326/0 is not valid, causing troubles to client using the href URL. It should be http://www2.terriscope.fr/geocache/tms/1.0.0/osm@WGS84/0 instead.

The same applies for http://www2.terriscope.fr/geocache/tms/1.0.0/truemarble@g that contains http://www2.terriscope.fr/geocache/tms/1.0.0/truemarble@EPSG:900913/0 whereas it should be http://www2.terriscope.fr/geocache/tms/1.0.0/truemarble@g/0

Even, do you have a tool that automatically displays a map given a tms capabilities url ?

Yes, GDAL trunk. It now returns the following : (I see the demo is updated in real-time. Before your fix, the was pointing to http://www2.terriscope.fr/geocache/tms/1.0.0/truemarble@EPSG:900913/${z}/${x}/${y}.${format})
