Though Bishop N.T. Wright is not Orthodox (he’s the Anglican Bishop of Durham), he explains very well the Orthodox/New Testament teaching on hell. This was originally entitled “N.T. Wright and the Orthodox View of Hell.”
This is only 3 minutes long, but a very nice treatment of a contentious topic – at least, contentious since the middle ages and the publication of Dante’s Inferno, Purgatorio, and Paradisio. The ‘tiered’ understanding of the afterlife is the origin of this false teaching about hell.
