dvddecrypter error: burn fine on DVD+RW, but not DVD+R

[canoner]

I used dvdshrink to compressed this dvd and got a .nrg image. It mounted to the virtual drive fine, and played fine. So I went ahead to burn it on a DVD+R, but at 81% it failed due to "cyclic redudancy ...". Then I burned it on a DVD+RW, and it went all the way! I thought there might be some memory shortage when I did the first burning, so I closed all the program, and tried to burn the image on a DVD+R again. It failed at the same spot! Why is it doing this to me? Why can it be burned on a DVD+RW but not a DVD+R? My standalone DVD player only reads DVD+R, that is why I have to insist on DVD+R.

What was the exact error?

Was it an I/O error stating 'cyclic redudancy....'
or was it a 'failed to read from file - reason: cyclic redudancy...'

Yes, it was "failed to read from file - reason: cyclic redudancy...". what I don't understand is I was coping a image file to dvd+R, so there is no scratch or anything like that, and I was able to copy it to a dvd+rw.

I am sure Lightning will give you the tech answer you require - you might as well ask the source for help after all :) - but if it helps I had the exact same problem when I got my first burner.

I could burn absolutely anything to +RW with Decrypter but try it to +R and it failed. To be honest I was about to pack it in when I tried a sample pack of +R media (previously I had only used the expensive brand that came with the burner) and hey presto! It worked with much cheaper brand stuff.

I don't know but I think it was something to do with the reflectivity. (could be talking complete a*se of course :p ).

I think the clue here is 'failed to read from FILE'

So basically, its not the dvd media that's causing the problem, it's your hdd having trouble reading itself.

I advise you to run a full surface scan of the disc. Maybe even move stuff off it, perform a low level format using the tools provided by the manufacturer and then try again.

Then why it went all the way when I burned the image on a DVD+RW?

the dvd+rw and dvd+r I used are both Imition 2.4x. I have successfully backed up about a dozen of movies this way on dvd+r.

I dont know! These read errors come and go. If you're positive that was the right error though, it's the OS itself that reported it - so you should trust it and run chkdsk/scandisk as I say.

But hey, if you dont wanna take my advice, it's totally upto you.

If I'm not mistaken, +RW is limited to 2.4x. Are your +R's 4x? It's just a guess, but maybe the issue is related to speed (heavy HD fragmentation at the 81% point?). Try lowering the burn speed.

[LIGHTNING UK!]

You can get 4x +RW. Not sure if his drive supports them though :-/

Finally I got it burn on dvd+r. I uses dvddecrypter to make an .iso image of the dvd+rw disc, and copied it back to the dvd+r.

In the middle, I defraged the harddrive. Maybe heavy fragment at 81% causes the problem, but I am not sure (considering how fast reading from hdd is compared to the 2.4x dvd speed).

My dvd burner can burn at 4x, but the batch of Imition discs I have are 2.4x only.
