[dvd::rip] Cannot rip subtitles

[Brian <brian@xxxxxxxxxxxxxxx>]

Hello.

I don't succeed in ripping the subtitles. I tried with "all subtitle"
and also only the german one.
I get:

It seems that transcode ripping stopped short.
The movie has 175050 frames, but only 1667
were ripped. This is most likely a problem with your
transcode/libdvdread installation, resp. a problem with
this specific DVD.

Ripping without subtitles works. Eventhough then the counter behaves
weird and counts far over 100%.
Any suggestion? Maybe I will get another Firewire drive to try again.
