I don't own Robot Carnival on DVD myself (and believe me, I would know if it was a bootleg if I did), but I seem to recall that Streamline did have a very limited release of some of their titles on DVD at the very end (can't remember who the distributor was, but I think it was after they split with Orion).
You had Area 88 on your list, so I don't think Venus Wars would be any less qualified.
