initialized. It remains some segfaults but it globally works.
. DVD mode is enabled with option --dvd. For the moment, it only read
the first vts and find the movie if it is at the beginning of the title
set.

Coming soon:
. udf filesystem management to access over 2Gb zones.
. detection of the offset to the movie inside a vts when it is not at
the beginning.

Is there a chance that using fopen/fseek function instead of open/lseek
system calls solve the 2Gb issue ?
