If your DVD will not play back in your computer, it's possible that your computer has a software conflict that prevents it from playing certain DVDs It's fairly common for Windows PCs to have trouble playing back DVDs, especially when more than one DVD player program is installed (for example, if Real Player and PowerDVD are installed). The programs interfere with each other and prevent certain discs from playing back.

It's normally easy to fix this problem with a free piece of software called VLC. VLC is free and safe to download and install on your computer.

To download VLC, go to http://www.videolan.org/ and click on the Download VLC link. This will download the appropriate version of VLC for your computer. Once you've downloaded VLC, double-click on the file to install VLC.

Once you've installed VLC, insert your Creative Catalyst DVD, and run VLC. In the drop-down menus at the top of the VLC window, choose Media>Open Disc or File>Open Disc and then click on Play. Your DVD will play.

If you are unable to play your DVD with VLC, please test the disc on another computer or on a set-top DVD player attached to a TV. If the DVD refuses to play back in any of these places, please contact customer service, and we will help you resolve the issue.
