I need help modifying one of the examples to start a roScreen

In the example "Video List Markup" from the "Scene Graph XML Tutorial", when I select an item "itemSelected", I want to rewrite "playVideo" so it's creating a roScreen so I can draw my own images on it. Is it possible?

sub init()
  m.top.backgroundURI = "pkg:/images/rsgde_bg_hd.jpg"

  m.videolist = m.top.findNode("videoLabelList")
  m.videoinfo = m.top.findNode("infoLabel")
  m.videoposter = m.top.findNode("videoPoster") 
  m.video = m.top.findNode("exampleVideo")

  m.video.observeField("state", "controlvideoplay")

  m.readVideoContentTask = createObject("roSGNode", "ContentReader")
  m.readVideoContentTask.observeField("content", "showvideolist")
  m.readVideoContentTask.control = "RUN"   
 
  m.videolist.observeField("itemFocused", "setvideo")
  m.videolist.observeField("itemSelected", "playvideo")
end sub

Sub OnChangeXmlstringscene()
  m.readVideoContentTask.xmlstring = m.top.xmlstringscene
End Sub

sub showvideolist()
  m.videolist.content = m.readVideoContentTask.content
  m.videolist.setFocus(true)
end sub

sub setvideo()
  videocontent = m.videolist.content.getChild(m.videolist.itemFocused)
  m.videoposter.uri = videocontent.hdposterurl
  m.videoinfo.text = videocontent.description
  m.video.content = videocontent
end sub

sub playvideo()
  m.video.control = "play"
  m.video.visible = true
  m.video.setFocus(true)
end sub 

sub controlvideoplay()
  if (m.video.state = "finished") 
    m.video.control = "stop"
    m.videolist.setFocus(true)
    m.video.visible = false
  end if
end sub

function onKeyEvent(key as String, press as Boolean) as Boolean
  if press then
    if key = "back"
      if (m.video.state = "playing")
        m.video.control = "stop"
        m.videolist.setFocus(true)
        m.video.visible = false

        return true
      end if
    end if
  end if

  return false
end function



If it's not possible, how can I replace the video playing screen with a screen that allows me to draw my own jpg images on it?
