I have been looking at this code and modifying for several hours and now my eyes are crossed. Any ideas why I cannot get events to print out? I'm sure it is something trivial.

sub showChannelSGScreen(contentid, screen)
  port = CreateObject("roMessagePort")
  screen = CreateObject("roSGScreen")
  m.global = screen.getGlobalNode()
  m.global.addfield("vidid","string",FALSE)
  m.global.vidid = contentID
  
  screen.setMessagePort(port)
  
  scene = screen.CreateScene("VideoExampleScene")
  screen.show()

  while(true)
    print "in while loop"
    msg = wait(0, port)
    msgType = type(msg)
    'print msg '
    if msgType = "roSGScreenEvent"
        print "showHomeScreen | msg = "; msg.getMessage() " | index = "; msg.GetIndex()
      if msg.isScreenClosed() 
          print "Screen closed"
        return
      else if msg.isRequestFailed()
        print "Video request failure: "; msg.GetIndex(); " " msg.GetData() 
      else if msg.isFullResult()
        print "Playback completed"
      else if msg.isStatusMessage()
        print "Video status: "; msg.GetIndex(); " " msg.GetData() 
      else if msg.isButtonPressed()
        print "Button pressed: "; msg.GetIndex(); " " msg.GetData()
      else if msg.isPlaybackPosition() then
          nowpos = msg.GetIndex()
          RegWrite(episode.ContentId, nowpos.toStr())
      else
          print "Unexpected event type: "; msg.GetType()
          nowpos = msg.GetIndex()
          print "Current position: "; nowpos.ToStr()
          RegDelete(episode.contentId)
      end if                
     else
        'print "Unexpected message class: "; type(msg) '
      end if

  end while

end sub

[NB_]

Because only roSgScreen is sending messages to that port? So the only prints you would see is when exiting the channel by pressing Back button, i would guess.

the quit messages aren't even firing either.

updated code still having issues

  screen = CreateObject("roSGScreen")
  m.port = CreateObject("roMessagePort")
  screen.setMessagePort(m.port)
  
  if contentid <> invalid 
      m.vidd = contentid
  else 
       m.vidd = ""
  end if
  
  m.global = screen.getGlobalNode()
  m.global.id = contentid
  m.global.addFields( {id: contentid} ) 
  scene = screen.CreateScene("VideoExampleScene")
  screen.show()
  
  while(true)
     print "in while loop"
    msg = wait(0, m.port)
    msgType = type(msg)
    print "msg"
    print msg
    print msgType
    if msgType = "roSGScreenEvent"
        print "showHomeScreen | msg = "; msg.getMessage() " | index = "; msg.GetIndex()
      if msg.isScreenClosed() 
          print "Screen closed"
        return
      else if msg.isRequestFailed()
        print "Video request failure: "; msg.GetIndex(); " " msg.GetData() 
      else if msg.isFullResult()
        print "Playback completed"
      else if msg.isStatusMessage()
        print "Video status: "; msg.GetIndex(); " " msg.GetData() 
      else if msg.isButtonPressed()
        print "Button pressed: "; msg.GetIndex(); " " msg.GetData()
      else if msg.isPlaybackPosition() then
          nowpos = msg.GetIndex()
          RegWrite(episode.ContentId, nowpos.toStr())
      else
          print "Unexpected event type: "; msg.GetType()
          nowpos = msg.GetIndex()
          print "Current position: "; nowpos.ToStr()
          RegDelete(episode.contentId)
      end if                
     else
        print "Unexpected message class: "; type(msg)
     end if

  end while
