.net - Microsoft.DirectX.DirectSound and TV Tuner

Question

Im currently using a WINTV Ministick from Hauppauge to stream to free TV channels. Whilst it works perfectly with the built in its native WinTv applciation, i cant seem to pick it up with the DirectSound API. The code im using to iterate through the devices is:

var cdc = new CaptureDevicesCollection();
    for (int i = 0; i < cdc.Count; i++)
    {
        lstDevices.Items.Add(cdc[i].Description.ToLower());
    }
    lstDevices.SelectedIndex = 1;

This only gives me my internal devices and the USB Web Camera i have as capture devices. Ive considered DirectShowNet but not sure if that will be able to pick up the USB stick either?

Anyone got any suggestions or sample code to do this?
