What kind of a DVD writer you are using? Is it old? Is it in a laptop? If in laptop - were you burning while plugged in a wall or on batteries? If it is one of the above (or all together :] ) then I'd advise to try burning again on some other drive. If your DVD got screwed up, then there isn't much to do with it besides throwing out or giving to kids to play with :] – Slink84 Aug 11 '09 at 8:48

I've gotten this problem a few times, there has been multiple causes. First, I'd check that the DVD isn't the problem by testing it on another computer or burning another copy. Make sure you burn at a slow speed (even 4x to be sure) and let it verify again. If all goes well and you still get problems, it's probably the drive. Check the connectors before tossing it though.

throwing a reboot into that mix of suggestions might help as well. – quack quixote Oct 20 '09 at 18:07

Well, looks like you burned a coaster (or have a hardware failure, but much less likely). No way to fix it other than trying to read it in a different drive that may have better error correction, or burning it again.

If you have been burning data through Nero and got an error (or stuck) on the 'verify data' stage, then most probably your DVD will not be usable. Try burning again, on another DVD (or with another drive, preferably).

If you really need to get that data off it, then you may try using one of the CD/DVD data recovery tools. Like IsoBuster, for an example.
