flash will not start automatically playing video and video advancement fails? - vb.net

Question

I am having trouble getting my current vb.net code to start automatically playing random video trailers retrieved from trailer addicts API service (I only return 6 of them at a time). In addition, I can play the first video but other videos fail to allow me to let me play them manually too with an error about protected memory being accessed. Here's the code:
Private Sub TrailerRotateTimer_Tick(sender As Object, e As EventArgs) Handles TrailerRotateTimer.Tick
If FirstTrailer = False Then
Select Case myoptions.TrailerPlayTime
Case Is = 60
TrailerRotateTimer.Interval = 60000
FirstTrailer = True
Case Is = 90
TrailerRotateTimer.Interval = 90000
FirstTrailer = True
Case Is = 120
TrailerRotateTimer.Interval = 120000
FirstTrailer = True
Case Else
TrailerRotateTimer.Interval = 60000
FirstTrailer = True
End Select
End If
firstvideo = myoptions.TrailerUrlCollection.Item(randnum.Next(1, 5))
' Video.EmbedMovie = True
Video.AllowScriptAccess = "always"
Video.FlashVars = ""
' Video.Playing = True
Video.LoadMovie(0, firstvideo)
If Video.IsPlaying = False Then
' Video.CallFunction("<invoke name=""id"" returntype=""xml""><arguments><string>100788</string></arguments></invoke>")
Video.Play()
'Video.Playing = True
'Video.Loop = False
Else
Video.Stop()
Video.Play()
End If
End Sub
Does anyone know what I am doing wrong?
P.S. here's the direct link I found to the SWF file if needed: http://v.traileraddict.com/js/flash/player.swf?id=100788&e=y&id=100788
