Re:Don't pre-judge the controller, folks
No, that would be a waste of resources, and would cause ugly tearing on all televisions due to the nature of interlaced TV. Imagine the worst case, where every frame you are alternating a clear to black or white. If you draw at 60 hz, you get this extremely ugly image that is black and white striped. If you limit to 30, you get exactly what you want: solid white followed by solid black.
It's true that newer televisions (read: HD) will update at 60 hz, but games are not taking full advantage of this yet, in the general case.

Re:Costs?
The basic reason why Classical requires better reproduction comes down to one thing. Dynamic Range. This is realted to distortion. In Classical, you want to record the original sound, completely free of distortion. You keep overhead available in your system so that the highs don't get distorted during amplification and recording. In most modern pop/rock/rap, distortion is used (on purpose) in the amplification to add to the effect in the sound.
Here is a link on Dynamic Range
Basic summary, the dynamic range is the ration between the loudest and quietest sounds. Rock/pop/rap is normally consistently loud, and hence a low dynamic range. Classical has very low lows and highs and as such has a very high dynamic range. That is what it comes down to. Here is another link on dynamic range Handel's "The Messiah Hallelujah Chorus" is one example of a classical piece that uses a high dynamic range. Beethoven's "Ode to Joy" 9th Sympthony is a very good example of one as it goes from quiet to loud (possibly the best example I can give). Jazz is the one other kind that typically uses this (that I know of off the top of my head). Look around for pieces of music that audiophiles use to brag about thier systems "Because it makes their system sound good".
I hope this clears it up somewhat. -
Yes, and documentation
In any setting the quality of cabling does matter. Or, more specifically, the quality of the connectors on the cable, and the quality of their installation.
Anyone who argues otherwise should recall that the first step in troubleshooting is almost invariably to check the cables.
While I am happy to use zip cord to wire my stereo speakers, I wouldn't trust dollar store cables for anything mission critical.
More important though is to document your cable runs, or even better tag each cable so that you have some idea where it begins and ends. You may know what goes into and out of that big ball of CAT-5 on the floor, but the guy who follows you will have no idea. -
Re:30 fps is a slideshow
This is not a response to you, but to everyone who thinks 30fps is enough: http://www.audiovideo101.com/learn/articles/hdtv/

Not too detailed...
Sure, it's great that the guy documented his project so others could replicate it, but it might be more useful if he mentioned how he calculated the optimal port length. Specs on resonance frequency, Vas, power handling, and other things might be nice as well. Or why he chose a ported sub rather than an isobaric or sealed design or something else. Not that there's a correct choice, but knowing a little bit about how and why he made his decisions might help others down the line.

Re:or you could...
But then again, TV is 240x480 or something, so you wouldn't really gain anyway.
If 640x480 is in the range of "or something" then you'd be correct. And at a 16:9 aspect ratio that most of these DiVX movies use, thte resolution would be more around 704x480, and that's viewed on a SDTV.

LaserDisc vs DVD - IANAVPIANAVP (... videophile), but I think presently the big downfall to the (ANALOG) laserdisc format is its direct encoding of composite video. The signal has been succeeded by S-Video, which offers unique channels for chrominance and luminance, and more recently component video, taking things further with multiple luminance-to-color based channels.
You can argue that a laserdisc only has 480 horizontal lines, compared to a standard 525 lines for DVD (it supports more using various techniques, but most movies still even only use 480). Yes, there are laserdisc players with S-Video out--these are nothing more than filters. You cannot get around the fact that the video is stored as a true composite signal on the disc. Inversely, you cannot get around the fact that a DVD, being compressed, will have artifacting--you may even be able to argue that this artifacting hurts the luminance quality more so than being limited to a composite signal (I would wager that in this scenario, component video would only serve to remind you further of the artifacts!).
So what's the real issue here? Don't get me wrong, I find everything about the LaserDisc to be very ingenious, but the fact is: I don't have to get my lazy ass off the couch, or potentially ruin a special 'moment' (either with myself or someone else ;)) to swap discs with DVD. ;)Not getting into the audio differences.
