Totally stumped... DVD image creation fails at 99% (even though it worked before, NO visable scratches or dirt on the disc!)

Title pretty much says it all...
The disc I am attempting to back up is a home movie recorded on DVD (so the original is a DVD-R as well, making the problem likely totally unrelated to copywrite issues).
This disc a week ago was analyzed by DVD Shrink, worked fine, wrote to an image just fine, recorded from the image fine, etc. No problems at all.
Today I attempt to put the DVD in, attempt to make a back up copy image with shrink... all is going fine UNTIL the process fails at 99-100%. I then get a CRC/cyclical data redundancy error.
Now, I know most of the time this error is received because the disc is dirty or scratched making reading impossible. Well, I cleaned the disc, examined it for physical damage (scratches and knicks), the disc is in very good shape and is clean. Didn't change anything.
I tried using DVD decrypter, no dice.
I tried using NERO to make the image, again no dice.
I tried reanalyzing the disc, no dice.
The disc plays fine in all players.
This is the only disc causing problems. All others work fine.
I have no idea why this is happening. I tried reauthoring the DVD in shrink... I can view files (that is to say they play fine) UP UNTIL I reach chapter 20. Once I attempt to view chapter 20, it turns to GARBLE. Once I reach chapter 20, not only is everything thereafter garbled, *but* everything before (which previously viewed fine) is also now garbled.
However, when I play the disc in a player and use powerdvd, all chapters play fine.
I really don't know what to do. I suppose I could always re-record the home movie compilation, but that's a LOT of work. Besides, this "error" might happen to another one of my dvds some time int he future, and I'd like to know what to do about it.

Perhaps I should mention my DVD specs.
I typically rip my DVD's to images using my DVD read-only drive (as it seems to be faster/more efficient). It's a lite-on. That drive model is JLMS XJ-HD165H.
My burner is a NEC ND-2500A
The original DVD was recorded on a MEMOREX Disc which should be high quality.
The only problems I've had with my drive so far have been related to stupid newbie mistakes. For example, before I had my drive in PIO mode which was causing cyclical data redundancy errors on almost anything I attempted to create an image from. Then I figured out I didn't have the secondary IDE controller checked "enable DMA" for both drives (the read drive was in DMA, the burner was in PIO... doh!). That fixed the problems up nicely.
But now I have this new problem, and can't figure it out. I really, really, really hope someone's heard of it (failure to create image @ 99% even though the disc is physically flawless, AND even though it worked fine before)

This might have nothing to do with your problem, but since you are getting so far (99%) before you have a problem, are you sure you're not burning too close to the end of the disc? Maybe you could burn, say, 4300mb instead of 4400 (or whatever Shrink's default is)? Would cause a bit more compression in Shrink, but still.
Other than that suggestion I'm stumped, sorry.
Karen H.--Dell Optiplex GX240, P4 1.50ghz, 256mb RAM (yeah, I need more), Windows XP Pro w/SP1, 80gb c: drive (replaced the 20gb c: that crashed), 126gb i: drive, 124gb j: drive, 500gb external hard drive partitioned into k: and l: drives, Sony DDU1621/C1 DVD-ROM to rip/encode, Sony DRX-530UL to burn, new Sony DRX-840U to burn DL discs ... need a new computer to go with it!!

Is it possible that you are trying to copy/burn an ISO file larger than 4GB on a FAT32 system??
This may cause some of your problems.

karen2003- thanks for the suggestion but that's likely not the issue, as the total size of what i'm trying to burn is 3.5 gb
colw- thanks, but its a NTFS file system.
Is there any way to "erase" dvd shrink's memory of having analyzed a disk already? I think perhaps this might be related to the problem... I think if I could just perhaps put it in fresh as if it never saw the DVD before and have it do a quick analysis again, I think that I might be able to do it.

Why don't you use the one you just burned?
Also if your making multiple copies of this home movie, save the image.

Just to be clear ... Are you saying Memorex is high quality?

flip218 - I wanted to make copies for both back up and for family/friends. I would have saved thte image but unfortunately I don't have that kind of hard disk space.
Well the memorex discs costed me like $70 from bestbuy so I should think they would be at least decent ;)
Sorry, but I am very new to all of this...

Thanks to ScubaPete for writing this:

Too many Memorex users here -
Memorex is an excellent example as media goes, figures as high as 50% coasters have been reported (One member bought a stack of 50 and got 23 good burns.), not what I would call an impressive record. There are 4 different companies that manufacture Memorex BTW and product quality varies widely as you might imagine. Easy to see now why the quality of a big-named company can?t be trusted - ? Who?s making your Memorex tonight ?? Note: Memorex in the singles, 5 or 10 pack, as a rule, cause less problem than those Memorex sold in bulk BUT they still aren't recommended for DVD backups.
1. * Cheap media freezes, skips, pixelats and may refuse to be recognized :-(
Besides "Freezing", "skips" and pixelations, many times you?ll get a ?Cyclic Redundancy error? or an "I/O error". This message can mean that your discs are scratched or dirty, it can also mean that your burner won?t accept your ?cheap? media :-(
Another problem which ?pops up? is a ?*Power Calibration Error?. This can stop you right in your tracks and most often is caused by, Yep, you guessed it, inexpensive media.
*A ?Power Calibration Error? can also be attributed to the Optical Components of a DVD Writer, though this isn?t usually the case. Trying to shut down your software and ejecting your DVD then restarting your program and re-inserting the same media recently cleaned has been known to help.
Inexpensive media or even average media is great for text, Data, Spreadsheets, .Jpg and .Gif pictures and is good even for MP3 music BUT for DVD backups - BLAaaaaaT! It SUCKTH in an extremely Big-th way !
2. A good grade media is needed for DVD reproduction !
?Branded? Ritek G04's or Branded Verbatim are what we?re looking for OR any media boasting ?Advanced Metal AZO.?, this indicates a superior dye application, while they are sometimes a bit ?pricey? they are acceptable.
Prices online from Meritline.com have gotten Ritek G04 starting at about a 1/2 dollar($ .50 USD) a disc -
Question - If you make coasters out of 3 cheap or even average discs and good copies from 3 Branded Verbatim discs or 3 ?Branded? Ritek G04 discs - which ones then will you say are too expensive ? The 3 ?Cheapo?s with no movie backup OR, the 3 recommended discs with a perfect backup on each disc ?
Bear in mind, Memorex, Fuji, Sony, TDK, Orange Pack and others are quite good for your MP3 music, picture archives, Spread sheets, Data and your text backups and archives, they just don?t work well for DVD backups. Even DataSafe G04?s made by Ritek have been reported as inferior quality and are evoking that ?Oh no, I shouldn?t have gotten those.?
Remember, for DVD backups, purchasing inexpensive media or even average media is a gamble, some people win, the majority of people lose, varying amounts but, they still lose :-(
Let's try the right media for the job - just buy a 5 pack of what we recommend that will settle it once and for all - Don?t cheat though, buy the EXACT media we recommended -
Using good grade media can guarantee you one thing to an absolute certainty; it surely cannot hurt.
BTW, In an effort to clear the air, when I speak of "Cheap" or "Inexpensive" media, I'm not referring to the price you pay at the counter - I'm referring to the type of composite some manufactures use, their method of dye application and the lack of OR the poor quality control used during manufacturing. when I say "Branded" that means that when you pick up a disc in your hand, it says "Ritek" or "Verbatim" on the disc itself. The monetary cost of the media we recommend many times is cheaper than that you are buying now.
cheers,
Pete
FAIR WARNING. . . Memorex users, using that "Cheap" media, your backups may not last all that long -
One thing I haven't addressed is the life of a backup made on an "el cheapo" disc. We all know that data, music and video backups on CD's and DVD's will last forever, well, if not forever for at least 100 yrs or so - That's what we've read and that's why we backup our treasures to disc, so that they'll be safe. "BLAaaaT" (the bone chilling sound of an emergency air horn), Wrong, Dead Wrong ! Don't throw the originals away, you may very well need them. Your video camera tapes and family pictures, may not be there the next time you want to look at them. "Point of fact," inferior discs have a tendency to "Break down" in time. In a very short time, we're talking disc breakdown in less than a single year, as little as 6 to 8 months. Important, please read -

flip218 - wow, thanks so much! that was really informative. I had no idea that memorex was inferior quality, AND i had no idea that data could "Degrade" over time. That might be the problem. However this stuff was recorded only 2 or so weeks ago. Could it really go bad that fast?
Fortunately, the memorex discs I bought i have ceased using. I learned of the superior quality (and price) of ritek G04's a short while ago and promptly bought quite a number from newegg. (Just so I'm sure, the ritek G04's from newegg are the ones with all the raving reviews, right ;)? they had a couple of ritek brands, but only one had about 200+ positive reviews so I figured that must be it and bought a few!)
Anyway, if the problem is that the cheap memorex discs have caused data to be lost, is there any way I can recover what I still have (it does after all only crap out at 99%, nearly 100% in fact_), or should I just record everything over on a g04?

I have one of those dvd cleaners, that has helped me before in the past. But if the source isn't able to be read successfully, the I think your out of luck. You could try running using Nero disc copy instead of making an image.

As far as Ritek's ... just make sure they say either Genuine Ritek's or Ridata and you should be fine.
