Recording a CD to a Wave file
This function uses the multimedia control interface (MCI) to control the CD drive.
Public Sub RecordWave(TrackNum As Integer, Filename As String)
'Tracknum: track to record
'Filename: file to save wave as

The method is quite easy:
1) Stop
everything in the CD drive
2) Start playing track
3) Record a new wave with the information from the CD (note: it
also records MIDI and microphone sounds: in fact anything coming
out of the speakers)
4) Save the wave file
5) Stop the CD again
