For me video is a generic term for a home viewable format of a recorded presentation: be it on tape, disc, or computer file. Even in a video store, I’d expect it to remain generic. And if I wanted to know if something were on a specific format, I’d specify which format.
I guess I’m the only one who though of “music video” having read nothing but the subject line. I suppose that’s the natural result of having been raised on MTV. I agree with the others though, it depends on the context of the sentence.
Since this isn’t 1985, when I hear “video” as used in the original thread, I think “DVD”. But then, I still talk about the new Magnetic Fields record even though I haven’t owned any LPs since the late 80s, either.
I always assume a VHS tape. My elderly mother uses the term frequently and I know she isn’t talking of a DVD (she calls them CD’s ).
The tape you put into the video machine.
My dad refers to DVDs as CDs too.
