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: 
[VirtualDub](http://www.virtualdub.org/) used to be the de facto standard for converting video files. It still does an admirable job.
I think that [Avidemux](http://avidemux.sourceforge.net/) can fit your needs.

Here's a recent how-to to convert your .VOB file to AVI (remember that AVI is just a container) : [Avidemux VOB to AVI](http://silverwav.wordpress.com/2010/04/19/avidemux-vob-to-avi-lightning-fast/)
