A few years ago I made some videos using the Showme app about the Homeric dialect and Homeric metrics. They are somewhat buried on the Showme site, so here are the two series, first on dialect, second on metrics:

Homeric Dialect 1 augments and endings: http://www.showme.com/sh/?h=JJqlpjc 

Homeric Dialect 2 the article: http://www.showme.com/sh/?h=C1XKW92

Homeric Dialect 3 verbs: http://www.showme.com/sh/?h=E9vmvB2

Reading Homer 1 Long and Short: http://www.showme.com/sh/?h=y2Su4LQ

Reading Homer 2 Quantity Exceptions: http://www.showme.com/sh/?h=0ArMTPU

Reading Homer 3 Dactylic Hexameter: http://www.showme.com/sh/?h=7trqGTg 

I think I made a fourth installment for the grammar series about particles, but I cannot find that on the Showme site. Hope you find these useful!
