In the directory where the AUDIO_TS and VIDEO_TS folders are execute a command similar to
growisofs -dvd-compat -Z /dev/hdc -speed=2 -dvd-video -V "DVD Label" .
The “-speed” option is only needed if one wants to divert from the standard speed. The “-V” option is to specify a label for the DVD. For more options see the manual page for growisofs and genisoimage.
