A DVD that can be played in a regular DVD player has a specific file structure, and contains a Video_TS and an Audio_TS folder with a set of specific file types. If you have ever backed up a DVD to your computer, or have attempted to create a DVD that can play in a regular DVD player, then you are likely familiar with the file structure. If you have a Video_TS folder stored on your Windows 7 computer's hard drive, play the video files in that folder using Window 7's default media player.
Browse to the Video_TS folder on your PC, then double-click the folder to open it.
Click the "Organize" drop-down menu at the top left corner of the window, then click "Folder and search options."
Click the "View" tab at the top of the window, then remove the check mark from the box next to "Hide extensions for known file types."
Click "Apply" and "OK."
Right-click on any of the files with a ".vob" file extension.
Click "Open with," then click "Choose default program."
Click the arrow next to "Other programs," then click "Windows Media Player."
Click "OK" to begin playing your Video_TS files.
You can select any ".vob" file in the Video_TS folder to begin playing the DVD video. Each of the files are linked to one another, so you can click the "DVD" drop-down menu at the bottom of the Windows Media Player window and click "Root menu" or "Title menu" to go to the DVD's menu screen.
