Can't play DVDs directly from HD from commandline

Hello all,

I've just installed the latest version of Ogle, and am sofar very impressed 
with it. :) The only problem I have is playing DVDs from the HD directly from 
the commandline (if I load the video_ts directory in the gui, it works fine). 
I've tried:
ogle /home/phulshof/multimedia/dvd/Lord\ of\ the\ Rings\ 2\ -\ The\ Two\ 
Towers/VIDEO_TS/
and
ogle -u cli /home/phulshof/multimedia/dvd/Lord\ of\ the\ Rings\ 2\ -\ The\ 
Two\ Towers/VIDEO_TS/
and
ogle -u gui /home/phulshof/multimedia/dvd/Lord\ of\ the\ Rings\ 2\ -\ The\ 
Two\ Towers/VIDEO_TS/
and the same things without the VIDEO_TS, but I keep getting the message:
Usage: ogle_ctrl [-h] [-u cli|gui] [<path>]

ogle_ctrl however does not exist on my system, so it cannot be started.

Any idea on what is causing this, and how I can fix it?

Regards,
