Frage for anyone who's watched the english dub!

Hey guys,
So i was watching a video with a panel of a few of the Eng dub voice actors and they mentioned an episode where they did commentary as their characters. I looked it up and apparently there's two episodes like that but they're only available on DVD? I have the DVD for the 2nd half of season 1 but i'm not sure if its on there (i'll check again though), if not does anyone know where i can watch it online? Asides from Funimation which wont let me sign in :/
