Does Manga Video still do films? Does the production company Manga Video, still produce films? For instance they produced the Ghost in the Shell movie. Do not produce films any more? If so, what happened?
Manga Video is just the distributor and co-producer of the anime Ghost in the Shell. The production company is, as hungerartist pointed out, Production I.G.. Manga Video only helped in production by contributing money.

To answer your question: Yes, Manga Video sill exists and yes, Production I.G. still produces anime.
