Next-gen DVDs: Expensive and confusing

[pp05]

Ok people say once you go HD you cant go back unless of course buying HD made you skint to go back.

What is worrying me about digital formats in general is longevity of the technology. VHS has 3 decades, CD have been around for a while, DVD only a short while etc...

[Stoo]

Umm..

CD's are over 25 years old, DVD's are nearly 10 years old.. (They'll be 10 in November)

VHS will largely have vanished over the next 5 years, CD's will still be going strong for a while yet, and there's loads of life left in DVD's, you'll still be able to buy them for a long time yet.

Yep, technology marches on, but it's nowhere near as bad as you're trying to make out..

whats more, is DVDs probably last longer than VHS degrade. Not to mention DVD has redundent parity. Same with CD.

DVDs and CDs decompose if they're not looked after... some types do anyway.

[steve threlfall]

DVD's are backwards compatible with HD and Blu ray players.

Oh heck yeh, all plastics do, they also breath and let in mosture.

Point is, compared to VHS, DVD seams "nicer" and therefore will last longer.

I'm sure when VHS first came out it seemed 'nicer' than film on a reel and a projector...

No, the quality was always questionable.

heck betamax was nicer than VHS.

HD to me sparks health warnings n such, not because of the typical TV aspect of it where "u sit 2 close u suppsoedly get square eyes"-but other health warnings.

ever wondered why humans get headaches/migraines from VDU's and TFT's?

easy
-----
Each Pixel lit up on th VDU or TFT you are on now is obviously emitting light,Because you're sat at a screen for over 2-3 hours at around 10-15 Inch's way of the same light emissions- it causes a strain on your eyes because the whole of the screen is too bright-even sometiems when brightness is too low it still can strain the eye-but the amount is small obviously
-thus giving u a migraine.

i think the real main concern here is that the more detailed images get and ability to focus on a certain part of the moving image-the more strain goes onto a human eye.


For E.G-i used to be able to sit a tv/pc screen for over 5 hours+ with breaks without no problems-but i have recently been for a eye test and according to what the Doc said is that due to being near screens /VDU's and TFT's basically all my 20 years so far- it has taken strain on my eyes and made my eyes worse than i was when i started wearing glasses over 14 years back.-nowadays even after one hour of playing a game on the pc -i get migraines,their aint much i can do except keep upgrading my glasses's every year.

Now im not judging /makin assumptions that HDTV is bad for us- the idea is good- i would love to watch my fav Porn movies in HD or watch england win the world cup.

to me- HDTV is overrated to me-yes i have seen the quality- but i cant exactly watch it over a 2 hour period with my eyesight. you all make it sound like we all need it asap-like its a mandatory thing in life like Bills and rent.

also it could spark major health warnings and i wouldnt be surprised that some numpty in this country tries 2 sue a maker for makin their eye eyesight worse....

the higher technology goes- the more health risks are along side it -I.E. onlien gamming can lead to no social life and even some cases of starvation and death or a keyboard can result in arthritis. it's the risk we humans take into a faster moving technology- if u can name me one technology that doesnt harm the human body in any way shape or form -then i will take it onboard obviously....

oviously i dont see any problems with BLU-RAY because it introduces another file format into the DVD media world- in which i wont be surprised that the supposed DRM that are on the discs when burned will be beaten...like any other file protection system. the only one that isnt beaten these days is supposedly StarForce.

most monitors/tv's have brightness controls, so if that were the case its the users own fault.

Secondly its nothing to do with brightness, but the fact that most old crt's and projectors run at 50hz and are flickery. Get a decent crt and run it at 100/160hz for a few hours, then change it back to 50/60hz and you will notice the difference.
