Thanks for attempting to use Nero CD-DVD Speed to check your suspect DVD for errors.
You do not need Nero installed to run Nero CD-DVD Speed. Nero CD-DVD Speed is a stand-alone program software utility program.
You do not want to have AnyDVD â€œactivatedâ€ when you are running Nero CD-DVD Speed.
I am at loss as to why you would be getting the error notification. Nero CD-DVD Speed is a very stable software program. Below is a Web Page that explains how to install Nero CD-DVD Speed.
If you are continuing to have problems with Nero CD-DVD Speed I would like to suggest using another software utility to check for errors on your suspect DVDs. The other software utility is called DVDInfo (http://www.dvdinfopro.com), which is also a free diagnostic software utility program. DVDInfo is not as a through testing tool for checking for disk errors and is not as definitive as Nero CD-DVD Speed but in most instances will find disk errors.
If you chose to use DVDInfo (http://www.dvdinfopro.com) to check your DVDs for errors the following is how you check for errors. Deactivate AnyDVD and place your suspect DVD in a DVD device. Install DVDinfo and open the program. On the opening page top menu bar is a Magnifying Glass Icon. Click on that Icon. The CD/DVD CRC Read Error Test page appears. On the lower right side of the page is a â€œStartâ€ button. Click on that button and let the program test for errors. Any Red (Bad) sectors indicate that suspect DVD disk has errors which is the cause of your failure to make a back up copy of this disk. As stated above DVDInfo is not as a definitive diagnostic tool as Nero CD-DVD Speed. If DVDInfo fails to detect errors does not rule out the possibility that the disk contains errors. DVDInfo just isnâ€™t as good of a diagnostic tool as Nero CD-DVD Speed.
