I don't know that E-On have a qualified hardware list, I've never seen one, and to be fair I've never had a problem running Vue off my Radeon. The reason the cards mentioned don't appear on qualified hardware lists is that these cards are consumer level cards not designed for graphics applications. ATI, like NVidia, have a seperate range of cards for professional work and it is these cards that are tested and certified for use. If its any consolation to anybody, my Quadro card is rubbish at games.
