Citat från tvtool.de:
Exception GF4-MX:
Usually the TV-chip is a single independent chip on the graphics card from a third party manufacturer like Conexant. These are supported by the tool. But with the GF4-MX nVidia introduces an own TV-chip NV17 which is integrated in the VGA chip and which is probably cheaper and less powerful than the external chips. For this chip there is no documentation available at all because nVidia refuses it. Without documentation a support cannot be integrated in TVTool!
