Hi there - first time post from a newbie. I've been copying using DVD-Rs now for about 3 months, really getting into it, building up quite a decent array of back ups but have a few important questions I would like to ask (at least they are important to me! lol) I have been studying the forums for quite a while and got some great info from some obviously very knowledgeable guys (and gals no doubt) but I am still left wondering the following...
1} Am I going to be left with hundreds of coasters in a couple of years? I check the copies after I make them and those that don't work (only a small percentage admittedly) I just throw away and redo. But my main concern is whether the ones that work now will still work in the future. Three months time? Six months? A year? Two? Five? I store them under decent conditions, handle them properly, but I do worry about the dye degrading as I have read in several postas and articles. Is this likely to happen? I have used all kinds of media - Datawrite Greys, RiVision 16x, Tuffdisc (but no more), RiDisc Extreme and not really had any problems other than with a batch of the Tuffdiscs.
2} Is there likely to be a more advanced copying system coming up a year or two down the line as technology keeps improving? If so, does anyone have any ideas what it might be, and when it might happen?
3} Do shop bought pressed DVDs have an expected lifespan? The reason I ask is that the odd DVD I bought back in 1999-2000 has frozen up occasionally where it didn't originally. Is this because the system was in its infancy back then and has since improved? Or will my rather huge collection all start to freeze up as time goes on? (I had a lot of laser rot problems in the late 90s with my lasredisc collection and do not want to go through that again!)
4} Are 16x DVD-Rs better than 8x DVD-Rs?
5} Why do most of my DVDs play better on my cheap Cyberhome (£25) and Yakumo (£30) DVD players than on more expensive Phillips and Sony models?
6} What is the best way to test a copy has copied perfectly? Currently I analyse using DVD Shrink. I thought the qick analysis would be enough but recently I found a couple of discs where the quick analysis went through 100% but the more detailed analysis did not. Is there a quick way to check or should I use the detailed Shrink analysis every time?
I think that will do for now, although if anybody can think of anything that leads on from any of my questions then I will be more than grateful to read it.
Many thanks,
Andy

Wow lots of questions.
In short, If you used crappy media, There's a good chance in a year or two you will have a giant coaster collection. Do a search for media and see what every one recommends. I use mostly sony that id's as TY's or tdk's seem to work pretty well. I've heard ridata & verbatim's are good also. I use verbatim DL's on occasion and like them. If it's the cheapest then It's either marked wrong or crap.
The best way to test a copy is to watch it.
The cheap players are more forgiving than the expensive tripple Progressive digital scan forwards and backwards models. They just read what's on the disc and spit it out.
more advanced method of backing up? sure. we're in the technology age.

To answer your questions:
1.) The time is takes for the disc to be rendered useless (under optimal conditions) is directly relative to the quality of the materials used in the manufacturing of said aforementioned disc. The higher quality (Ritek, MCC, some MKM, and TY) discs are more likely to give you five+ years of service than lower quality (CMC Magnetics, some TDK, fake TYs, some Maxell, etc.), which can begin to show problems almost instantly after (or during) the writing process.
2.) With the advancement of video and audio streams, there will invariably be an advancement in copying them. An example of upcoming technologies is that Dolby is going to use an extremely-high bitrate lossless audio with HD-DVD movies. So, yeah.. there are things that the future holds. There will always be a way to copy audio and video. It just has to be invented.
3.) yes
4.) Assuming both are manufactured by the same companies: Only if you want to burn at 16x with a lower chance of errors. Everyone here will suggest you write between 4-8x, even on 16x discs.
5.) The semi-realistic reasoning I can come up with is that companies like Cyberhome and Durabrand constantly "update" their product lines with new versions of their players. When doing this, I assume they use the latest firmware/media codes for maximum compatibility.
6.) I have no idea. I suppose you could use Nero cd-dvd speed and use the read test.
I hope I'm accurate on some of that,

This force, evolution, is not sentimental. Like the Earth itself, it knows only the hard facts of life's struggle with death. All you can do is hope and trust that when you have served its needs faithfully, there may still remain some glimmer of the life you once knew.

Lots of good answers here. I will just make a little addendum and add my 2 cents, for what it?s worth..
1) If you are using cheap, crap Media, Yes. I have a tub full of degraded Memorex, Imation and other crap media that I cannot play or recover.. The cheap, thin dye does degrade.. I now use ONLY Verbatim 16X +R with Advanced AZO metal coating?. Check this link:
http://www.digitalfaq.com/media/dvdmedia.htm
2) Yes, but I have no idea other than guessing what it will be.
3) Probably, but since they are pressed they will last a lot longer than the burnt by laser to a coating will. Technology has improved and the newer disc will probably last longer.
4) All I can say is: Will a tire that is warranted for 50k miles last longer than one that has a 25k mile warrantee? Yes.. Even at that I always drive sensibly, that is, I burn at ½ the rated speed of the disk. For 16x rated, I will burn at 8x, for 8x burn at 4x, etc. etc. Driving slow makes them tires (Discs) last and work better?..LOL
5) Answered, Progressive scan?
6) To test my DVD Burns I find the fastest and easiest way is to put them in my Expensive, Progressive scan DVD Player and Fast Forward.. If it runs thru without baulking or stopping with a screwed up screen, It?s OK??
