OK Don, how about this site http://www.dvddemystified.com/dvdfaq.html#4.10

The salient points from there are.. 
"The .IFO files contain menus and other information about the video and audio.
The .BUP files are backup copies of the .IFO files. The .VOB files (for
DVD-Video) and .AOB files (for DVD-Audio) are MPEG-2 program streams with
additional packets containing navigation and search information.

Since a .VOB file is just a specialized MPEG-2 file, most MPEG-2 decoders and
software DVD players can play them. You may need to change the extension from
.VOB to .MPG. However, any special features such as angles or branching will
cause strange effects. The best way to play a .VOB file is to use a DVD player
application to play the entire volume (or to open the VIDEO_TS.IFO file), since
this will make sure all the DVD-Video features are used properly.

Many DVDs are encrypted, which means the .VOB files won't play when copied to
your hard drive. (If you try to play the copied VOB files, the decoder will
request the Decryption keys from the DVD-ROM drive and will fail. You may get the
message "Cannot play copy-protected files".)

If you try to copy the .IFO and .VOB files to a recordable DVD it may not play."

There is loads more info there on this...
