You can use Finder, Disk Utility, iTunes, iPhoto, or iDVD to burn files into writable CD or DVD. Apple Support has a summary guide on how to go about [burning a CD or DVD](http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh854.html). If you want to burn a disc image file (commonly in ISO disc format and with an ISO extension), a separate Apple Support article describes how you can [burn a disk image file on a CD or DVD in Mac OS X](http://support.apple.com/kb/HT2087).
However, if you have DVD Video files in VIDEO_TS folder, there is no quick method using the bundled apps in Mac OS X to burn a DVD-Video disc to be playable in regular DVD players.
[Burn](http://burn-osx.sourceforge.net/Pages/English/home.html) is an open source and free app that can help you burn the disc to the correct DVD Video format.
Or if you prefer the command line using Terminal, the steps are:
* Create a new folder to house your VIDEO_TS folder, for example ~/Downloads/XMas2008/VIDEO_TS.
* On a Terminal session, enter the following command:
hdiutil makehybrid -udf -udf-volume-name MY_DVD_NAME -o MY_DVD.iso /path/to/folder/containing/VIDEO_TS
Using the above example:
hdiutil makehybrid -udf -udf-volume-name XMas2008 -o XMas2008.iso ~/Downloads/Xmas2008/
* Make sure that /path/to/folder/containing/VIDEO_TS is the path to the folder containing the VIDEO_TS folder, not the VIDEO_TS folder itself.
* The command will create an ISO disk image file XMas2008.iso.
* Start Disk Utility, drag the newly created XMas2008.iso into Disk Utility and click the Burn button to create the DVD-Video disc.
