If you have a problem with DVD's created by Studio not playing back, these steps will help to resolve that issue. This FAQ assumes that you have put the DVD into either:
1. a set-top DVD player and the DVD is not playing (there may be an error on the display panel of the DVD player)
OR
2. a DVD drive on your computer and it won't play
If one of these two applies to your situation, then skip down to the section called "Troubleshooting step for DVDs…..", otherwise, you may have a different DVD playback issue so read the FAQ's below that may be more appropriate to your particular issue.

Troubleshooting step for DVDs created by Studio that do not play back or appear blank
1. Check the disc for cleanliness. Ensure that there are no obvious smudges or scratches on the disc surface. If the disc is dirty, clean it with a soft cloth by wiping the DVD from the center of the disc to the outside edge. Never clean in a circular motion.
2. Insert the DVD into a DVD drive on the computer.
- Double-click on My Computer.
- Then, right-click on the drive that the disc is in and choose Explore.
- See if there are folders on the disc.
There should be two folders on the DVD. These folders are AUDIO_TS and VIDEO_TS. The AUDIO_TS folder should be empty. The VIDEO_TS folder should contain .BUP, .IFO, and .VOB files. If there are files on the disc, then Studio burned the DVD, and this is definately a playback issue.
If the disc is in fact blank, there is a burn problem rather than a playback problem . In this case, follow the instructions in the FAQ on burn problems in Studio. Click here to see the FAQ on burn problems in Studio.
3. Try playing back the DVD on the computer. The disc should play back with DVD player software such as PowerDVD and WinDVD. Windows Media Player (WMP) may not play DVD's, and whether it does, depends on your version of Windows. If you have problems playing back your DVD on your computer, click here to read the FAQ titled, "Playing DVD's on your computer"
4. If the DVD will not play on your set-top DVD player, then we recommend that you try to play it on other set-top DVD players. Some DVD players may not play a certain brand of DVD or a certain DVD media format (i.e. -R, +R, -RW or +RW).
Make sure that the DVD player will play the type of media being used. Check with the DVD player manufacturer’s website to see what disc formats it supports. Another good place to check for compatibility is:

If the type of disc being used is not supported by the DVD player, please try a different disc media format.
you do If find that the DVD plays in one DVD player but not another, then the DVD player, then you should burn the project again using a few different brands of DVDs and types of DVD's to find a combination that works for that particular player. It is also possible that the DVD player is starting to fail (or have problems reading writeable media).
NOTE: When troubleshooting all burn or playback issues, it is recommended to use rewritable media to avoid wasting discs.
5. Make sure that the project you created is set for the correct playback format for your region (NTSC for North America, PAL for Europe). If it is not set for the correct format, the disc you create will also be in the wrong format and some DVD players will not be able to play back the disc.
You can check the format that you project is in by placing your mouse pointer over the project name in the Timeline. When you do this, a tooltip will be displayed that gived project information. See the following image for an example:

In this case the project format is NTSC Widescreen. This is what should be displayed if you live in North America. If you live in North America and this tooltip says PAL, then the disc that is created will be in PAL format and will not play on all players.
The project format by default is set by the first clip that is added to the project. So if the first clip you add is NTSC format, your project will be in NTSC format. If the first clip you add is PAL format, the project will be in PAL format. This is the default method of selecting the project format in Studio. This can be seen by going to Setup -> Project Preferences. In those settings is a section called "Project Format". See this image:

If you are only working with NTSC footage, but your project is set to PAL, you may have selected the "Use this format for new projects" option seen above and selected a PAL format. Make sure that you have "Set from first clip added to project" selected and purposely add a clip with the desired format to the project first, or alternately you can select "Use this format for new projects" and select a format that is appropriate for your region.
