I understand about copyright and all that for TNG, DS9 and VOY, but here's the problem. I love Enterprise, but why are some ENT episodes unavailable for viewing. Since most of the episodes are available, why aren't all of them? For example, the major plot gap at the end of season 3 that would be resolved by the missing first 3 episodes of season 4. I don't think this is very fair to those of us who can't watch any Star Trek series any other way, because it is never on TV.
