DVDs have had a comparatively notorious reputation when it comes to reliability, so it's very important to use good media and check the data on it. Nero DiscSpeed, under Nero Toolkit, allows you to check for disc quality. Select the Disc Quality tab and insert a burnt disc into the drive.

Make sure you have the DVD drive selected from the drop.{\own menu at the top and click Start. The software gauges the quality of the burnt disc. A final score will be shown in the Quality score field on the right. On Internet forums, you'll find a lot of such media scan posts. Run this test on different kinds of media you've burnt so you know which media works best with your drive.
