Hello. I am experiencing an issue where the "resume" and "start from the beginning" buttons appear when a live feed has been exited. The buttons behave as expected on mp4 content but I am trying to remove them from live feeds which are supplied through a xml file. Can someone point me in the right direction? Thanks.

        item.ContentId        = validstr(curShow.contentId.GetText())

Try adding refreshShowDetail(screen,showList,showIndex) under the While True line in appDetailScreen.brs under the function showDetailScreen
It may work.

Thanks. but that didnt work.

As far as I can see, you're not treating HLS differently anywhere. You're doing the RegWrite of the video position for both live and VOD, which causes your refreshShowDetail function to create the resume button. If you don't want that behavior, check whether your content is live (or is HLS or whatever condition you want to use) before writing the position to the registry in your event loop.

thanks. that helped. wound up using this.

Function refreshShowDetail(screen As Object, showList As Object, showIndex as Integer) As Integer

    if validateParam(screen, "roSpringboardScreen", "refreshShowDetail") = false return -1
    if validateParam(showList, "roArray", "refreshShowDetail") = false return -1

    show = showList[showIndex]
    'Uncomment this statement to dump the details for each show
    PrintAA(show)
	
    if show.contentformat <> "audio" and show.streamformat <> "hls"
        screen.ClearButtons()
       if regread(show.contentid) <> invalid and regread(show.contentid).toint() >=30 then
          screen.AddButton(1, "Resume Playing")    
          screen.AddButton(2, "Play from Beginning")  
          screen.SetStaticRatingEnabled(false)	
         else
            screen.addbutton(2,"Play")
	        screen.SetStaticRatingEnabled(false)
        end if
        screen.SetContent(show)
        screen.Show()
    else
        screen.ClearButtons()
        if(m.playing = 1) then 
            if(m.paused = 0) then
                screen.AddButton(1, "Pause")
            else
                screen.AddButton(1, "Resume")
            end if
            screen.AddButton(3, "Stop")
        else
            screen.AddButton(2, "Play")
        end if
        screen.SetContent(show)
