I am unable to choose the place where twonky should search for media. That is in SHARE/Content Locations of the GUI. How do I do this.

For example
I am thinking that I would like to have a HDD added per USB. How can I point twonky to these files when it scans for media?

I thought that this was changed by the twonkymedia-default.ini which looks like this

contentbase=/shares/MYVOLUME1/MYSHARE1/Music
contentdir=/
friendlyname=Twonky MSS
dbdir=/shares/MYVOLUME1/MYSHARE1/Twonky/twonkymedia.db
httpport=9000
enableweb=2
scantime=90
maxmem=20000
platform=MSS

I have for a couple of days now posted a similar question in the twonky forum but have had no response and as the wl700g is not supported by twonky I think that I made a mistake posting there first. So please spare me the forum rules rant.
