Re: DVD Disk Verification Issue

Hmm, our duplicators are setup to copy the original to hard drive and then burn and verify from that. I didn't think the LED on the drive itself would show any sort of verification error, but I could be wrong. The duplicators software should be setup to verify 100% and during that stage the error should be more precise.

Have you tried burning the master using a different drive? We have about 15 plextor drives and a few of them cannot burn anymore. They produce a dark circular band on the bottom of the DVD-R which is full of unreadable sectors and thus cannot verify. However they all will play fine on our settop DVD players. Still NOT good though.

Oh and they have to verify from the original master/image. If they don't there is no verification.

As far as the burn area on the bottom of the DVD is concerned, I think that has to do with how different drives write the lead-in and lead-out as well as the padding packs. I have made copies before and the burn area is half the size of the original yet it verifies fine within our Eclipse premastering system (which does a bit-to-bit comparison.

First thing I would do is burn a new master with a different drive. Other than that see if they will accept an image file and they can produce the copies from that or at least create a new master for you. That way you can send the image on a hard drive or FTP. this eliminates any sort of problem you will have in the burning process.

Oh also you can also download a program called "Beyond Compare" it does a great job at comparing files from one source to another. That way you can see if some of the information is being changed before you send to your dupehouse.

I hope this helps.
