Since i own a PS3 i like to stream all my movies to it. Sadly the video support in it as of date is pretty poor, but it can play .vob. Sadly most movies "borrowed" from the internet is encapsulated into a .iso or .img files, that is iso9660 for us mortals... ;)
Anyway, upon mounting an iso you will find, if it's a dvd rip of course, two folders VIDEO_TS and AUDIO_TS. The VIDEO_TS contains the whole movie segemented into a s*itload of .vob files.
Each of these files contains x-minutes of the movie. So what you can do if you don't like changing movie file every other second. Merge the files together as one large vob. This can easily be done with a cat *.vob new_file.vob command.
But as i'm lazy by nature i wrote a script doing all this for me. I found a nifty cat progress bar implementation called Bar to see the merge status as cat has no progress report of it's own.
So here goes, my extract-vob script. Ps. Sorry about the indentation, i blame the blogs wysiwyg.
