DS9 on blu ray?

For a listen or two, until the needle starts to gouge them apart.
Naw, I don't think so. It certainly has nothing to do licensing. It would be part of the technical specifications, not licensing per-say.
480i is an allowed resolution, according to http://en.wikipedia.org/wiki/Blu-ray_Disc#Video
Many BD releases port over the previous DVD bonus content and it's stored as 480i just as it was on DVD.
Of course for marketing, a company would never release a main feature as 480i, even if all they did was upscale it before hand, it would still be stored as 1080p to simply make a marketing buzz word.
I think the point that was being made is that BD releases cannot be SD-only. That's not to say that they can't include any SD content, but that a BD release must contain some HD content.
This is what makes it a licensing issue, rather than technical. BD, at its core, is just a storage medium just like a CD, DVD or even magnetic tape. So, BD is capable of storing pretty much any digital content you'd like, but to license BD for a home video release it must contain HD content.
Exactly. The same applies to film, currently Citizen Kane will outlast Toy Story, in all honesty I'm not sure it deserves to (both excellent, ground breaking films).
People are working on it, but long term digital storage is currently a right mess, blame our throwaway culture I guess.
I don't believe there are technological issues preventing Disney from outputting Toy Story to film so that it can rest alongside Citizen Kane.
But being on film is no guarantee of longevity, and there are a distressing number of films you and I will never have the opportunity to see because they've been lost to posterity.

I believe that is exactly what they have done, ironically. It is odd though that with all the advances we have had an archivable digital format still doesn't exist isn't it?
I didn't say it was a guarantee, only that treated well it has a tendency to last far longer than any digital format.
Ironically of course, a lot of those great lost movies and tv, be it the full cut of Magnificent Ambersons, or the early Doctor Whos, were actually actively destroyed. Sadly we will never have a technical solution for vandalism.
I know hard drives fail. There are moving parts, etc. But has anyone had a CD or DVD die specifically because of age? Scratches, yes. Corrupted, yes. But life span? Is it that they will certainly die at some point, or they are not guaranteed past a certain amount of time? Because the former is certainly different than the latter. CDs have been around for a long time now so some of them should be scooting past their shelf lives at this point, no?
I don't know...I was recently trying to create a Win 7 install disc using rewritable DVDs I purchased a few years back (less than a decade, anyhow) and every single one of them failed to verify. Some I'd used before for other things, some I likely hadn't used, but when I tried burning to a new disc I had no problems.
It's also all up to the manufacturer of those discs as not all are created the same (some cost more than others)
Cheaper discs are probably designed and manufactured cheaper. I know there's not much difference between discs, but there isn't much difference between cassettes & I have had cheaper cassettes end up useless far faster than others I used regularly.
I think the longevity issue with digital media (music/videos/programs) isn't too much of a problem.
Yes Hard Drives can fail over time, discs can wear out, scratch, snap..... But there is nothing stopping anybody from copying that media onto new discs or hard drives every so often (backups)
And if they are stored in similar conditions as film, there shouldn't be an issue.

Exactly.
[Annoyingly though, I can't find the source I had on that a couple of years ago now. Although I can't find any counter-examples either...]
There have been some problems. Not universal - the discs in question were poorly manufactured - but if the substrate breaks down, the same world happen to other discs: http://cdrot.com/info/why-are-cd-rotting-how-it-happens/
Rewritable DVDs are a different technology from pressed (mass-manufactured) DVDs, though. DVD±RW are less reliable than DVD±R, which are MUCH less reliable than DVD-ROMs (and even within the technologies, there are variances depending on manufacturers and so on).
Well, the material of CDs and DVDs just rotts slowly. The plastic gets dry and fragile and the metal between the plastic layers rusts if air gets to it. Pressed media have a better quality then CD-ROM, so the latter material will break down quicker. I am already thinking of ripping my Audio CDs from the 80s and 90s (hundreds of discs), so I still have the music when the CDs dont work anymore.
If it comes to long term accessablity, analog media is still the way to go. If you want to make sure you can look at your photos when you are old, you have to develop them. If you want to make sure you can read ebooks and other texts when you are old, you have to print them out. Everything else is in the risk to get lost. Not only because the storage media doesnt work anymore but also because maybe in 30-50 years there is no reader for the digital files any more. Or because of dementia you cannot handle digital files and readers anymore (but even in the latest stages of dementia you can look at your old photos if they are on paper).
The governments are already aware of that. I know the US government is converting important information from todays time to analog media and stores it somewhere deep in a cave, so in 10000 years it is still readable. They use metall (gold?) plates to engrave texts onto it (in a spiral form, beginning with large letters and ending with microscopic small ones) or crystals with holographic stored information. Here in Germany the government holds a warehouse with old computers to make sure, they have a device to read old digital data (remember the big old tapes, floppy discs or datasettes?).
One day "Voyager" might be the only information about mankind that exists in this universe, once we are gone.

Well, LP's are made of Vinyl and can last a thousand years if cared for properly.
I'll let ya know sometime around 2132: http://en.wikipedia.org/wiki/LP_record
I think the VOY fans are probably following along in this thread.I find it funny how there seems to be next to zero interest on VOY getting on Bluray release. There is not much of any demand from even Trek fans!
Nothing lasts forever. If we want proven longevity, we have to transcribe film scripts onto cuneiform clay tablets.
"Long term storage" means keeping them at 45-50 degrees in low humidity.
A single average summer day in the American south is enough to mess up most old LPs. They warp pretty easy. If you were to leave a vinyl on a dashboard of a car in direct sunlight it won't just warp but begin to melt...and the destruction of whatever analog data was on the record would have degraded about 50-75 degrees before that.
