You don't need any program to make an MPG file from DVD (*.vob). Make a *.bat file with the following code - depends how many *.vob files your DVD contains:

copy /b vts_01_1.vob + vts_01_2.vob + vts_01_3.vob + vts_01_4.vob outputFile.mpg

Don't include any vts_xx_0.vob file as it is non editable menu. If your DVD has more than one track (separate video) it need to be converted to MPG separately. Additional tracks are numbered vts_02_x.vob, vts_03_x.vob etc.

For most DVD authoring programs it's preferable to demux = separate MPG container into audio and video. The best is Project X as it allows to cut unwanted parts as well: http://www.videohelp.com/tools/ProjectX or http://www.videohelp.com/tools/PVAStrumento
