encode2mpeg uses spumux/spuunmux to demux/mux dvd subtitles.
if they are missing, then no demux is possible.

Install dvdauthor and pay more attention to the output messages.
I suspect you will get more of them :-(.

Also keep in mind that:
1) text subtitles conversion is not a well tested feature.
2) results vary a lot depending of the ocr engine. Also I remember
I had better results with tesseract 2.01 than 2.03, but probably
it depends of the graphics subtitle source.
In any case DO NOT use any vertion of tesseract newer than 2.03.
3) until you are sure you have all the needed tools installed,
use a simpler command line: extract only one subtitle (-addsub 0),
extract only a small part of them (-addchapter 1-2), copy the
dvd image to the hard-disk and use -dvd-device <image_path>
it will speed-up a lot your tests.
4) be prepared to hand edit the extracted subtitles.

Ask here if you still have troubles.
