If you just burned the Video file to a DVD disk, you did not make a DVD Video.
The reason you can not play that disk on the computer may be because your computer does not have the required Codec to play the video file.
A DVD video is made in the Create Disk Module and has a AUDIO_TS and a VIDEO_TS folder on the disk.
VIDEO_TS contains the video files. The files are in VOB format.
Or you can burn a Bluray disk if your videos are High definition.
