sub ShowEpisodeScreen(show, leftBread, rightBread)

  Dbg("episode url: ", show.url)
  Dbg("episode rss: ", show.content)

  mrss = NWM_MRSS(show.url,show.content)
  content = mrss.GetEpisodes()
  if content.Count() = 0
    ' TODO: show an error dialog
    return
  end if
  
  if false

	screen.SetMessagePort(CreateObject("roMessagePort"))
    screen.SetListStyle("flat-episodic-16x9")
    'screen.SetListStyle("flat-category")

	selectedEpisode = 0
	screen.SetContentList(content)
  end if
        if true
            screen = CreateObject("roGridScreen")
			screen.SetGridStyle("four-column-flat-landscape")
            'screen.SetDisplayMode("scale-to-fit")
			screen.SetDisplayMode("photo-fit")
            screen.SetMessagePort(CreateObject("roMessagePort"))
            doCerts(screen)

            numrows = content.count() + 1
			selectedEpisode = 0
            screen.SetupLists(numrows) ' count of rows
            labels = []

            row = 0
            col = 1
            gridarr = []
            for each i in content
                gridarr.push(i)
                if col = content.count()
                    labels.push(leftBread)     ' ("row " + str(row))
                    screen.setContentList(row,gridarr)
                    gridarr = []
                    row = row + 1

        if msg.GetIndex() = 13
          if content[selectedEpisode].streamFormat = "mp3"
            ShowAudioScreen(content, selectedEpisode, leftBread, "")
          else
            ShowVideoScreen(content[selectedEpisode])
          end if
				end if
			end if
		end if
	end while

I don't really understand your description of the problem, but it sounds like maybe you might want to add a return statement after msg.IsScreenClosed() instead of an exit while. If you want to pass data back to the calling function then make it a function instead of a sub and return a value.
