Video keeps looping ads

I had gotten this code

'A full RAF integration Example:

To play ads on this code

'** Video Player Example Application - Video Playback

'** Create and show the video screen. The video screen is
'** a special full screen video playback component. It

'** understand what's going on, especially in the case of errors
Function showVideoScreen(episode As Object)
if type(episode) <> "roAssociativeArray" then
print "invalid data passed to showVideoScreen"
return -1
port = CreateObject("roMessagePort")
screen = CreateObject("roVideoScreen")
'Uncomment his line to dump the contents of the episode to be played
while true
msg = wait(0, port)
if type(msg) = "roVideoScreenEvent" then
print "showHomeScreen | msg = "; msg.getMessage() " | index = "; msg.GetIndex()
if msg.isScreenClosed()
print "Screen closed"
exit while
elseif msg.isRequestFailed()
print "Video request failure: "; msg.GetIndex(); " " msg.GetData()
elseif msg.isStatusMessage()
print "Video status: "; msg.GetIndex(); " " msg.GetData()
elseif msg.isButtonPressed()
print "Button pressed: "; msg.GetIndex(); " " msg.GetData()
elseif msg.isPlaybackPosition() then
nowpos = msg.GetIndex()
RegWrite(episode.ContentId, nowpos.toStr())
print "Unexpected event type: "; msg.GetType()
end if
print "Unexpected message class: "; type(msg)
end if
end while
End Function

 The problem is that the ad keeps looping instead of playing the intended video
