  Dim SrcAud As IWMEncSource
  Dim SrcVid As IWMEncVideoSource
  Set SrcGrpColl = Encoder.SourceGroupCollection
  Set SrcGrp = SrcGrpColl.Add("SG_1")
  Set SrcAud = SrcGrp.AddSource(WMENC_AUDIO)
  Set SrcVid = SrcGrp.AddSource(WMENC_VIDEO)
  ' Replace the following name with the name of your device.

  Set DControl = DCColl.Add
  ' Replace the following name with the name of your device.
  DControl.SetInput ("DeviceControl://Device resource name")

  Dim DCPlugin As IWMEncDeviceControlPlugin
  Set DCPlugin = DControl.GetDeviceControlPlugin

' Retrieve a WMEncEditDecisionList object from the device
' control plug-in.
  Dim EDList As WMEncEditDecisionList
  Set EDList = DCPlugin.EditDecisionList

' Create an EDL entry.
  Dim EDData As IWMEncEditDecisionData
  Set EDData = EDList.Add

' Add attributes to the EDL entry specifying mark-in, mark-out,
