4.VOY
5.ENT
I think the Next Generation was the height of Star Trek (esp The Best of Both Worlds). It's to bad that the Gorn didn't appear though.
2.TOS-I only saw this in reruns, but it's still good.
3.Voyager
4.DS9
5. Enterprise-I never really liked that series, especially when compared with TNG and the original.
I also have every Star Trek movie at home.
Voyager

Enterprise
TOS
Why I stopped watching Star Trek I don't know, It's great (well I don't know about Enterprise being good because I never have seen it)
I do :grin:
Does seem odd
The biggest problem is when charactors talk in Klingon. It should be instantly translated, but it isn't :lol: .
Official designation for the original series is simply Star Trek or TOS (hence, The Original Series)...
As for the sound issue, here's a few bits of advice...
Space is never a complete vacuum. There's always some bits of matter in space, hence a tiny (but present) amount of 'atmosphere'. It may be a pressure in the order of microbars or something, but there's a pressure in space and if there's a pressure it's also possible to have pressure differences and variations -- hence sound. The only problem is that the human ear is simply not sensitive enough to get these minute variations, when the sound is transferred onto a ship's hull (vibrating matter bouncing off a ship's hull). Suppose they put ultra-ultra-ultra sensitive microphones in space... they'd probably pick up loads of noise from everwhere. Although I doubt they'd hear a ship 'whoosh'-ing by. 
The velocity of a sound wave= square root of gamma*P/p
Where gamma is the ratio of heat capacity in a constant volume and heat capacity at a constant pressure, P is pressure, and p is the density of the substance. In deep space with atoms a few feet from each other there would be no pressure and therefore the answer would be 0.
I know there are some real world hydrogen propulsion ideas based on large hydrogen scoops, but I didn't know this was used by any fictional Federation craft.
Yap. On the front of the nacelles there are the Bussard ramscoops (the round spherical thingys on the TOS nacelles) which collect both deuterium (for the main fusion engines) and antimatter (for the warp drive) drifting in space.
The atoms being tens or even hundreds of feet apart doesn't prevent them from interacting with each other. Gravitational forces can go a large distance even on the atomic level, although the intensity of the pressure waves would decrease rapidly. Doesn't mean it's nonexistent though, the current equipment available can't measure pressure differences in the order of nano- or picopascals (or less) since that's already way beyond their noise threshold.
Simply put: If we can't measure something, not instantly assume it's not there. This turned out to be the case with many things including the atom which is now general knowledge but they couldn't measure such a thing back in the '20's (scanning-tunneling microscopes weren't built back then) but still they theoreticized it would be present.
And the Enterprise is actually venting gas (plasma) when it's travelling at warp speeds. Remember Picard always chasing the ion trail of a baddie's ship? It's got to come from somewhere and since plasma (including warp plasma) is ionised gas, it would be a quick reasoning (although a little imagination is still required) that high-velocity, high-temperature gas (in ionised form) is pushed into the nacelles, it does its job (generate a warp field) and the excess matter (low-temperature, low pressure but still ionised gas particles) would be expelled out of the nacelle grilles. That's also the trails you see when Enterprise jumps to warp (both in the movies and on the Star Trek: Enterprise series).
Should I drop more (somewhat) interesting André Bormanis theorires here or should we keep it at this?
André's done a nice job on the whole Treknology issue, BTW. Anyone seen his new series Threshold? Brent Spiner in a totally different character 
Antimatter (as far as 21st centunary physists know) doesn't exist anywhere outside Fermilab and CERN (I live very close to Fermilab btw). One of the major questions in physics today is CP violations, which means when the universe was made there was just a very small fracion more matter than antimatter; the reason why we don't live in an antimatter universe today. So the Enterprise would have to make its own.
To collect signifigant amounts of hydrogen they would need a collecter several hundred miles long, but it's possible that the Bussard ramscoops are used when going though nebulas.
Interestingly there is a theory that it's possible to go faster than light by bending (warping) space.
Oh, I don't know. Some sci-fi's that do this have a sort of etherrealy beauty to them. Especially in battle scenes.
If you were designing ships for centrefugal gravity, they'd look nothing like the ships in Trek (which are all designed for gravity plating, which might be possable but I'm going off from my point here). For an example of what I mean - The human ship and station designs in Babylon 5 (which is generally acknowledged to have the most realistic ship designs within television sci-fis)
Babylon 5 is indeed one of the few shows which makes space travel and colonisation really credible. Also details like, all of the current nations and beliefs still exist in 2359, FTL drive isn't shipbound for the smaller ships (jumpgates are a very real concept, also used in Freelancer) and more things make Babylon 5 one of the best thought over sci-fi shows of the '90's. Also remember that the computer graphics they did back then can easily be reproduces by the current desktop systems... in real time! (just start up X3: Reunion or Freelancer and you'll see!)
The Firefly universe by Joss Whedon is also a very credible one, no aliens, no FTL travel, man has taken centuries to colonise one star system. Most of the technology you see shipboard (especially on Serenity) is actually scavenged from aircraft scrap yards. (I've actually got an aspiration to build a working (simulated) flight deck of Serenity one day)
