A VOB file is a container for data, just like AVI or MP4 or MKV is. It contains video, audio, subtitles, menu information, all combined together. See http://en.wikipedia.org/wiki/VOB

If you encode the video to MPEG 2 making sure all parameters are within what the DVD standard wants, the program creating the VOB files won't need to re-encode everything again, it will just copy the video and audio into the VOB file and add whatever information is needed. HCenc (or other mpeg 2 encoders) should create the mpeg 2 file (or should have an option to restrict encoding to DVD standard) in such way that the vob creator won't need to re-encode the video.

As for x264, the indexing of the video file is just a quick parse through the whole content, to get a clue about how long the video is, the frame rate and other things, it does no encoding at this point so that's why the processor usage is low. It probably has to do this indexing because you have a raw video. With an AVI file where the video is compressed using Lagarith or another codec, it shouldn't have to index the content.

Anyway, once it indexes the file, it should start encoding using all your processor and as fast as the hard disk can read the video from disk.
