Code:
#Start <InsertDisc.avs>
BlankClip(length=100,width=544,height=576,pixel_type="YUY2",fps=30,color=$000000)
SubTitle("INSERT DISC 2",-1,-1,0,framecount()-1,"Arial",15,$FFFF00,$000000,5,0)
#End <InsertDisc.avs>
Just encode this to an avi file and I would personally do this to a seperate avi file and add it as a clip to the vcd and put its "wait" time to infinite. That way it shows after the moive and stays there like a menu until they either A. Hit a button or B. Remove the cd.
Hope this works/helps ;p
