When I drop the "//dev/sr1", mplayer tries to read from sr0, but there
is no disk.
So I tried with:
$ mplayer -dumpstream -dumpfile CYD_dump+nav.vob dvdnav://0//dev/sr1
Then I get the message:
DVDNAV, switched to title: 1
... and again I only get the 70 kB file.

With:
$ mplayer -dumpstream -dumpfile CYD_dump+nav.vob dvdnav://1//dev/sr1
it seems I get the real video ... it's now working ... let's wait for
the result.
