VLC is open source. If you don't trust that it won't set your DVD region, download the source code, read through it, and then compile from source. That's probably more than most people want to do themselves, but you can bet someone has, and if the software were doing something sneaky, there would be one helluva stink (it's basically _the_ media player for Linux/BSD/BeOS/Solaris/QNX/etc. etc. etc., and the open Unix OS's have plenty of source-code-scanning fanatics)
You can at least read this info from the vlc website, and this from the libdvdcss site. That's the library vlc uses for dvd decryption. These are both established and well-known projects, so I'd tend to trust the documentation that nobody's trying to scam anyone by just setting regions and not telling. Anyway, it's not really that hard to read from a DVD without setting regions - the CSS encryption scheme is highly broken.
