Quick Way, just rename the VOB File to MPEG example video_ts.vob to video_ts.mpeg. The VOB is really a mpeg with another extension on it.

There is another way which is this procedure posted on the wrigleyvideo.com website.

Once setup, this is an easy and efficient way of importing VOB (DVD) files into Premiere without the need for re-encoding video.

First you will need:

Adobe Premiere AviSynth Import Filter Plugin - http://urchin.earth.li/~tomford/avisynth/index.html
AviSynth - http://www.videohelp.com/tools?tool=Avisynth
Microsoft .NET Framework - http://msdn2.microsoft.com/en-us/netframework/default.aspx
MeGui - http://www.videohelp.com/tools?tool=MeGUI

Once you've got these installed, ensure you update MeGui so that it downloads the latest version of DGIndex then watch the tutorial video on how to use them.

This also works for MPG/MPEG videos.

Although MeGui features a "D2V creator" I had problems using this, hence I load DGIndex separately.
People have mentioned renaming the ".vob" extension to something else such as ".mpg" or ".avi" I've tried this method and found that any edits aren't as precise once rendered and sometimes premiere will give an error about being an usupported or a damaged file.
