OAV, OVA | Volume, EP etc.

[Ravlie]

Hello,

As the title says I would like to know when to use the... abbreviations?

So far as I know all anime titles start with an episodes and after the end of a story of anime there's an OAV or OVA airing out. I don't know the meaning of OAV, OVA after all the episodes.

Also I want to know why hentai's titles are starting with Vol. 1, 2, 3 not Ep. 1, 2, 3 (sometimes even OVA)? I know Volume is a collection of chapters from manga so why when they release a video it's still called volume not episode? Why authors stick to volumes when they release their videos (I even saw sometimes OVA 1 - Vol. 1?).

Thanks for explaining this to me and probably other people.
