Has anyone ever heard of, or have any experience burning movies onto "Nexxtech" DVD+R discs? I have never heard of this disc and "Circuit City" currently has a sale on this disc.

Nexxtech just like Future Shop's Philips, Imation, etc are all used for coffee or beer coasters. In other words they are sh_t. Please stay long long long away

Hello Binky7
Thanks again for your warning on the "Nexxtech". While I was in "Circuit City", I saw - at least 7 packs of 50 of "Nexxtech" go out of the store. The "So called" Tech people there were saying that "Nexxtech" is basically the same as "Sony", "Tdk" etc. They had no reason for the comparity, I asked them..... So much for tech advise from circuit City"
Thanks Again Ronnies

I actually bought a pack of these at Circuit City. The ID is "AML-002-00" which I realize is at the bottom of the low along with CMC-MAG. However, the burning went fine using DVD Decrypter. All I got was an error when the DVD was being verified (after the burning stage), I clicked cancel, popped the DVD in my DVD Player, and it works fine.
So I'm going to continue using these until I deplete the pack.
Can somebody tell me how DVD's can go bad over time? I don't really understand this... once an image has been burned, it should work forever. What is this test of time bullshit?

Hi there,

Even if a burning software says Sucessfully Burned 100% doesn't mean the quality is there.
Some burners can do a PiPo Scan (Quality Test).
Most if not all cheap media, will get results of 50% right down to 0% quality.
It's called a DVD Burner, since it burns a layer of dye on the disk, facking little holes (A bought CD or DVD are pressed, not burned).
Now most cheap media use a low quality dye.
Doing a PiPo Scan on them, tells you if those fake wholes are easy or hard to read.
After a few tries, the DVD player may still be able to read it, but not on the 1st shot, since he's not sure if it's a 0 or a 1.
After time, 6 months, 1 year the dye (Not sure what it does) proabably changes form, the holes get harder and harder to read, making a media real hard to read.
Comments anyone ?

There are several parts of a DVD that contribute to its ability to playback over a length of time:
1) A. Substrate--DVDs have two halves that are molded in a slightly convex shape. As the bonding agent cures, it pulls both halves flat. Changes in flatness (caused by paper labels, poor quality printable coatings that shrink, poor adhesive, or improper storage) will cause the outer edges of a disc to move out of focus.
B. The lower half of the disc has to have very precise molding geometry and be free of imperfections from the stamper such as almost invisible debris that gets between the injected plastic and the stamper. These kinds of problems usually show up right away with a disc failure.
2) Dye--the dye is organic. Heat from the recording laser darkens spots to simulate the molded pits in a DVD-ROM so that the reading laser light does not reach the optical sensor on playback. The dark spots have to be precise lengths in just the right multiples of each other and have sharp contrast ratios between light and dark. If the lengths deviate (jitter) or the contrast decreases over time as the dye breaks down (as it will for ALL discs--it's just a matter of how much time), then errors increase to a point where error correction can no longer fix them. Heat and humidity are the two enemies of all organic dyes.
The dye has to be constantly filtered and evenly coated across a disc to avoid tiny congealed clumps that result in "dye comets" as the dye spreads past the clumps. If large enough, the clump will cause such imperfect recording spots that fatal errors can occur immediately during recording or quickly over time as the dye changes.
C. Metal mirror layer--silver alloys are used as targets for the evaporative electron beam that deposits the silver mirror layer over the cured dye. Those targets and the vacuum chambers have to be perfectly clean and free of contaminants. Some early DVD+R discs failed over time as black spots from contaminants appeared in the alloy layers. Pure gold is also used a reflective layer, and this resists humidity and corrosion better than silver alloys but does not reflect as well as silver.
Imperfections in any of these materials or the assembly will cause early failure of a recorded disc. Mishandling is the other cause, and that is beyond the manufacturers' help.
