Can I backup a dvd backup?

how much of your CPU are you using. How much of your RAM is currently occupied. I'm sure if I just installed a new operating system without anything else, I could probably run the program at 500MHz at 64-128MB ram. I do have other things on my computer that run in the background and have minor CPU usage. This is why software has recommended and minimum requirements. It's always best to run at the recommended requirements, but that's not the topic on this forum, or are you still having trouble focusing.

I'd swear you were cockeyed if you could just try and look at me straight.

[Doramius]

glad you have a dictionary near. Very close, but not quite the exact. Try looking at a dictionary for the military.

800 Megahertz Duron, 512 MB SDRAM 40GB Western Digital hard drive, 80 GB Western Digital Hard Drive. Emprex 8x Dual Format DVD burner. Btc 52x24x52 CD Burner. Are you happy? I am not an idiot.

[gitreel]

I too am in the IT Industry. I had a classmate that had the same attitude as you and thought he knew everything. He dropped out, because he found out he wasn't as good as he thought.

[Doramius]

I never said you were an idiot. I said you can't focus. Thanks for proving my point, AGAIN!

whatever. You still do not need a 2gig processor to burn dvd's. I have proved you wrong.

[Doramius]

A classmate? You're still in school, as in you haven't graduated or finished college? I knew you had to be looking at some text somewhere. I go to school, too, but I already have 2 degrees in this. There is a reason why ruby laser is the most common, but maybe you haven't learned that. However, not all lasers in optical drives use the same identical technology, partially due to patents. No if you want me to continue the lesson, we can start a new forum. Or you can learn a bit before we go further. You should've dropped out if you weren't going to pay attention to your professor.
----
I'd like to take credit for Know it all, but when I figure out how your brain works, I might accept the label.

[Doramius]

You might as well go to another forum. You're getting boring and digging yourself deeper into a hole, just like the other time you spoke of. I never said you HAD to have a 2.2CPU to burn DVDs. I said it's best to stay at the recommended system requirements. Go to bed and chill. Take a Ritalin and some asprin. It'll all be okay tomorrow.

[gitreel]

speaking of acronyms. do you know what scuba stands for. let's call a truce. My point was that nobody knows everything.

[Doramius]

I do know what SCUBA means, but I only dove once in my life down in FL when I was....a lot younger, but didn't care to learn much about it. I'll call a truce that nobody knows everything. I'm not trying to impress you or anyboody with wits. I've got others who'll school me hands down. I just wish people will pay attention to detail and try understanding a bit. I don't need to come to a forum and explain to the very detail of why my method works. I'm just trying to get the message across that I have done something that works.

[gitreel]

ok truce it is. You ought to try diving again. It is fun. Although I need a refresher couse. I haven't dove in about 6 years, since I got my advanced open-water cert.

> glad you have a dictionary near. Very close, but not quite the exact. Try looking at a dictionary for the military.

I spent 25 years in the military. I don't know of any reason a dictionary for the military would be taken as better than any other dictionary. Perhaps you should try a German dictionary or some other language- you can always pick and choose what definition you like.

[Doramius]

Let's stay on topic in this forum. 2 of us are at a truce, we don't need anymore arguing in here.

[BobK]

Let me rephrase then- why would anyone assume that a dictionary for the military would be any more accurate than other dictionaries unless you're dealing something specifically military.

Take it however you want, but I'd like to know the answer to that.

[johns0]

Doramius,you are right about dvd with errors but properly burned dvd`s do not have these errors and can be reburned over and over as long as no errors get introduced on the way and all the dvds will be identical,same as if you burned a data folder with critical files,as long as its burned with no errors all the files can be retreived.

[Doramius]

Just so we can get this out of the way and leave this forum for people who want to know if they can back up a DVD:
----
try looking up certain medical terms or words in a dictionary, even unabridged (odd they would call it that when it says unabridged). Try looking up IT certain technical words or terms. Especially acronyms, a dictionary will grab a term or word and throw it in according to what pop culture is defining it. In the military, where LASER was created, they would have an actual term: Light Amplified by Stimulating Emitted Radiation. Same thing as naval SONAR for aquatic radar, or diver's SCUBA for a breathing aparatus. With LASER, gitreel was basically on the money. Most people would wonder how it is different. This is because the beam, which is called the LASER is already amplified from emitted radiation. It's just a gramatical thing you notice in dictionaries and text books. It is essentially the same thing and that's why I said it was close and said he must have been looking at a dictionary. I really didn't want to go into a whole detail on it.
----
Now let's keep this back to the main topic.

[Doramius]

I agree johns0. Let's go to a previous example I used.
----
You'd think for a company like SONY they would make their players 100% compatible to read all of their dyes in their burn media. it's not so, but for the sake of this example we're saying they are. ( I also use Ritek 90% of the time, I just use the name SONY as an example. i could call it LEGO or Aunt Jemima if I wanted, but some people might get confused a little more and people here are already having a hard time paying attention.)
----
We take a store bought DVD movie. We pop it in our Sony DVDR(w)burner, whatever format it is. Let's say DVD dash R. We burn the movie and play it on a Sony DVD Player (and any other pleyer that will read the media). Now let's copy the clone using what we'll call [perfect] media, or media we'll say does not have traditional imperfections, errors, or scratches. We will get a 100% copy of the original and can do it on down the line. (CLONE OF A CLONE OF A CLONE.......) They will all be 100%. The data read off of the disc, if copied 100% completely, will create an exact duplicate. Your chances of this grow slim here in the real world. I've gone as far down as 16 generations on identical media brand with the same burner. I had to RMA my PS2 for that one. I didn't have a MOD chip or anything on it either. I was mainly using it as a DVD Player and a few games I bought. I have a Panasonic and Sanyo Player that both got very hot on that movie. It didn't phase the Emerson or the Phillips/Magnavox players. Using different media brands each time I got about 4 generations on another movie, but used the same burner. Using the different burners, but identical media, I got a little bit of mixed results, but they ranged from 6-10 generations. Using different media and different burners, I got a load of mixed results ranging from 2-8 generations. I'm going to try and make it to 20-25 generations on my Emerson and Phillips/Magnavox players and see if I can phase them using identical burner and media. I have a bit of a way to go.

I was having touble making a backup of a DVDXCOPY backup, and ended up making 4 coasters til i got the process that worked,
insert dvdxcopy backup in dvd rom drive, open dvd shrink, click on open files "not open disk". open the ts video folder. then click re-author and drag main movie only over, then click backup. it worked perfectly.

btw, in only use dvdshrink now, it is a great program. i can cut out all the extras and then get a very high compression rate for just the main movie.

[chicola]

Just more 2 cents...

A digital copy IS a digital copy. No question!

But MTBF is a factor present in all devices and, as so, despite the perfection of the media you will have from time to time a "digital copy" which won't be so "digital"!

Lock this resurrected thread before it has a chance to EAT MORE BRAINS!

[musotechy]

what about making a copy of a copy after using DVDxcopy to make the first copy? it seems like you can only make 2 copies?
any way around this?? ive tried with roxio and nero and it hasnt worked

Yes, use a good bit of software in the first place, all copies of DVDXCopy should be gathered in to one place and burnt, preferably in the warehouse where they are made.

Get DVDShrink

I don't know what Lordsmurf is talking about, but he's a smidge off. Digital IS all 1s and 0s, but if lordsmurf is correct about the technology, then the different media would have nothing to do with it.

Incorrect, media has a massive effect on it's content. I have been running a digital harddisk recording studio for around ten years now and whilst most CD's play fine, clarity in the pro studio discs is comparable to the difference between tape and CD. If it's like this in audio, I am pretty sure it will be the same for visual as well (not forgetting the audio in the film too)

why do people use file verification or file comparers?

the basic fact is that a digital copy under perfect conditions could be reproduced a million times or however more as lordsmurf mentioned. You may get faulty burns that are not the same but if you wanted to copy copies (in whatever field you work in) then you would have some sort verification process and throw away any rejects. Most places would probably just have a Master Copy anyway

as for DVD backups, I would dare say that the only copy you couldn't guarantee was an exact copy is the first copy you make as who is to say the DVD-ROM will read it correctly in the first place?

but once you have that copy on your HD and burn it and then verify/compare it OK what are the odds it is still not a bit for bit copy? Very slim I would reckon. Add one speck of dust (or whatever) to that equation then you may eventually have differences copying a copy of a copy etc

so theoretically you can keep copying the copy and depending on the circumstances and your requirements determines whether you will get an exact bit for bit copy

It just depends on how life threatening it is to you as to whether you keep making perfect copies of copies but there's more to life than worrying about degradation on copying DVD backups

Muso,

The only effect media can POSSIBLY have on its content is whether or not the content burns properly in the first place.

Please do not do us a disservice by perpetuating the idea that "mastering" CD's are in some way superior to other CD's. The simple fact is that I can retrieve the same 1's and 0's I put onto a CD, regardless of what type of CD it is or how much it cost, so long as it meets a certain MINIMUM QUALITY LEVEL. Beyond that level, the only difference is durability, shelf life, or perhaps how well certain players will like it.

Is there NO point to buying more expensive mastering media? I never said that. Durability is important, shelf life is VERY important, and the capability to be read back perfectly in the widest variety of readers is of EXTREME importance... but in a high quality drive, my $0.10 TDK 700MB/80Min. disc reads and records IDENTICALLY to your $10.00 mastering disc.

"what about making a copy of a copy after using DVDxcopy "

U cannot. Xcopy puts a copy protection on it so you cant' copy again.

NO IT DOES NOT.

DVD XCopy merely detects when it has already copied something once, and won't do it again.

Examples:

1. You make a copy of "Independence Day" with DVD XCopy. DVD XCopy won't make a copy of this copy, but any other program will.

2. You make a copy of "Independence Day" with DVD Shrink. DVD XCopy will copy it, no problem, as will any other program.

3. You make a copy of a copy of a copy using Nero, because after all copies have no protection. Then you run DVD XCopy and it corrupts your hard disk. Serves you right for buying such a crappy program.

If i understand u right, u have a dvdr which has been ripped and re-encoded from an original.

Use dvd decrypter in iso mode to read the dvdr, this will store on yr hd, then change the mode to iso write, select the file from yr hd and it will burn onto a blank.

Thanks for this piece of advice, Jaffa. I was finally able to backup a dvd-r that was giving me all kinds of problems using this method.
