I am currently trying to fix some calibration related tunings, to enhance reception. If you have Windows, you can participate to the following experience : - Download and launch USBSnoop 1.8 : http://benoit.papillault.free.fr/usbsnoop/index.php.en - Connect the USB tuner - Check which driver correspond to the USB tuner ( "Present" = "Yes" column ) - Unplug the USB tuner - Disconnect the aerial. - Click on "Install" for the driver corresponding to DVB tuner - Replug the USB tuner - Launch the TV app. - Select 2 or 3 different channels ( there is no picture as there is no antenna ) - Unplug the USB tuner - You shall now have a pretty big LOG file, copy-it ( "View" button ) - Zip that log file. - Send it to me : Thanks in advance.
