Oh, ok. I considered this as a possibility, but your mount point
deceived me. :) Had I been more careful I would have realized that
"GLADIATOR" wouldn't be there if it were a DVD.

In most cases it's better to use -dumpstream, rather than copy the vob
files:

mplayer dvd://1 -dumpstream -dumpfile title-1.vob

...will copy the entirety of title one into a nice, big, unencrypted
file. The only thing you might want to get directly from the mounted DVD
is vts_01_0.ifo, if you plan to use subtitles. My understanding is that
the ifo file contains information about the color palette to use when
rendering the subtitles; if you don't use it, the subtitles look ugly.
Then, once you want to encode, you would do this:

mencoder file-1.vob <options> -ifo vts_01_0.ifo
