Here is what I did in Videoplayer with the appDetailScreen.brs find this area in the 4.1 SDK files. You have to do this twice screen.SetStaticRatingEnabled(false) that's it.
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()
End Function
