MP SETUP
Television, Capture Cards, Add, "Hauppauge WinTV 88x TS Capture (Hauppauge HVR-1100)"...
ERROR: "Unable to create graph for this device"
If I re-select the card, the button "Autotune" appear but if I click autotune...
ERROR: "This device deos not support auto tuning"

With analogic-section and DVB-S card it's all ok.
Can you help me?
Thanks
