Nero read error copying a 4.7 GB DVD-R movie
 

Nero gets a read error when copying a 4.7 GB DVD-R movie

Tried DVD shrink out of curiosity and it did the same

Is this a software problem - in which what do you recommend to copy ?

The disc plays perfectly on more than one home DVD player.

Try DVDDecrypter
Obviously, beware of copywright issues when copying DVD's though ;)

DVD decrypter you can tell it to ignore faults so you will get a copy

Ok, trying DVD De-crypter and its come up with the same read error - will tell it to ignore and hopefully I'll get a copy out of it!

If you are using a DVD-ROM to try to read the image, you'd be better using your DVD writer to read the disc as they have more powerful lasers and tend to rip 100% successfully where a ROM might struggle.

hmmm that is a statement i would not entirely agree with.

Anyway, it sounds like the disk is screwed/scratched etc... best bet is to give it a clean with a rag, try DVD Decryptor as previosuly suggested, failing that then just try to copy files (.vob, .ts) to your hard drive from within Windows and then create a new dvd image from Nero.

Scratching a DVD-R on purpose is also sometimes used as a copy protection method. Often dummy files are added to the end of the disc and a small scratch is made in the final written area of the disc to produce read errors, but the disc will still playback fine.

Have not used this DVD software before - downloaded it, but can you advise what the best method is to use it to back-up to 4.7 Gb DVD's. Basically, I see there is an option for only the movie files - is this what I need?

Secondly, what is the differences between the modes - File, IFO and ISO Read and ISO Write?

Bit cr*p at this stuff - but would like to learn. Anyone talk me through it so I can understand it? Thanks

Normally you can just use Nero to copy one 4.7GB disc to another 4.7GB blank

For *backing up* an original DVD movie (which come on 8GB discs called DUAL LAYER)

You have 2 options:

1) If your burner supports DUAL LAYER, just pop a DUAL LAYER blank in and copy it with Nero Burning Rom

2) If your burner doesn't support DUAL LAYER, then download DVD Shrink which will compress your original movie down and burn it onto a 4.7GB blank

You're better taking a look at;www.dvd-recordable.net as there's a bit more to it than the above post would lead you to believe.

I agree with this statement 100% writers are better readers

My thanks - downlaoded DVD Shrink and DVD De-crypter and both work like a dream to the extent I can make back-up copies (literlly only one required for our holiday home) and it will compressjust enough each time to get the movie on the 1x 4.7gb disk. Works perfectly. Thanks very much for the tip - I now feel well informed!

odd.. cos id agree with him

its the same with cd writers etc its true to say that a writer can infact rad disks much more accuratly then a plain reader

If the writers reading speed is faster than just a DVD Rom it will be better by nature.

read speeds got nowt to do with it, writers are just better made and have better lasers.. and they are much less fussy over disk imperfections

It's the disc that determines how 'fast' you can read it.
Try checking a burned disc with Nero DVD Speed or equivalent and it'll produce quite an informative graph reflecting the quality of the blank media you've burned.

This is why an 8x burn isn't half the time of a 4x burn (burning on-the-fly)
A typical disc can be read at approx 4x for the forst 1gb or so and this should pitch up to a maximum of about 12-16x by the time it reaches 4gb

Using 16x media, you won't be burning flat out until about the last 20% of the burn...hence 6-7mins for a 16x burn or 4.4gb

Writer's don't read faster than roms. Quite the opposite infact as manufacturers tend to cap the read speed to 8x to prevent burning out the laser.
You can flash hacked firmwares to allow faster rips but you're not doing the drive any favours.

I've lost the point i was going to make.......
