Merci pour vos reponses.
Mon probleme c'etait ca :
"Another kind, less sophisticated, is called Macrovision blocking (at least that is what I call it). This blocking prevents any DVDs from being played back through the tv-out, even if the tv-out is directly connected to the TV set, making DVD playback on your TV totally impossible. Most Nvidia based cards use the BrookTree chip or the Chrontel chip, below is a table of the different chips, which manufacturer(s) uses them an and methods to remove Macrovision :"
Et la solution est bien d'utiliser TVtool :
"BT869 Diamond, STB, Leadtek ... may also work with Creative and other cards based on the NVIDIA reference design Enabled by default, can be turned off with Tv-Tool 3.03"
Donc merci encore a vous deux.
