You could try connecting on a USB port other than the hub. Do you have much in the way of settings or is it fairly automated. You can play the capture before you burn to check the sound on some software, I am not familiar with this one. You do not mention a connection to your line in for the audio, sometimes there is a "Y" shaped connector with the red % white phono plugs going to a 3.5mm minijack, unless you have phono sockets on your computer. Did the Scart come with the package as it needs to be "in the correct direction"
