[CentOS] Unable to write video dvd using k3b

Hi,

File command on above giving the below ouput.

file VTS_01_1.VOB VTS_01_1.VOB: MPEG sequence, v2, program multiplex

file VTS_01_2.VOB VTS_01_2.VOB: MPEG sequence, v2, program multiplex

When i opened any of the above files using vlc or kaffeine it is playing the movie properly.But when i try to create the video dvd file onto my dvd using k3b its giving error "Not able to find DVD format".

Plz help me how to write this into dvd to watch this movie in normal dvd player.
