Question: Does anyone know of a good freeware application where I can convert a full VOB file into a MPEG file. All of the applications I have found are trial versions and will only convert a part of the video.

I just need to convert one VOB, do not plan on using it long term.

Answer: 
VOB files are already in mpeg format as described [on wikipedia](http://en.wikipedia.org/wiki/VOB). You can just rename them to .mpg. You might need to set windows to "show file extensions for known file types". If you copied this file from a DVD that used some sort of encryption (most DVD's do) you will first have to decrypt the DVD using tools described on doom9.org.
Try [VOB2MPG](http://www.svcd2dvd.com/VOB2MPG/default.aspx). There is also a Pro version with additional features, but for simply converting (or rather, remultiplexing) VOBs to MPG files, the free edition is enough.
