Need help with bahn.de!!!!!

Hi All!
I am trying to look at the prices of train tickets on bahn.de but the only options of start and end stations that I can see there are Amsterdam, Rome, Berlin and Paris......are these the only stations between which the German trinas travel???? I am sure that is not the case so probably I am missing out something on the website.....can anyone tell me what may possibly be going wrong????
And also it would be great if someone may help me in looking for train tickets from Zurich to Venice. the sbb.ch website does not show the prices online and I have already raised a request with them for the tickets that I may be interested in.
Thanks.

Did you get to this page? http://www.bahn.de/international/view/en/index.shtml

I didn't have any problem typing any city/station in the boxes on the left and could find info on the Balkan Express I was looking for. However the price of Zurich to Venice was unavailable. Under 'Fare' it said

Fares not available Tariff abroad
For connections outside of Germany, a special ticket is required. These offers are not bookable via the internet.

Tickets may be purchased in any DB ReiseZentrum, authorised travel agencies or over the telephone using DB ReiseService by dialing 11861 (toll call).

Go to http://www.reiseauskunft.bahn.de/bin/query.exe/en and type in the stations/stops that you are interested in.

The site records destinations you have typed in before. If you are logged in from a hostel PC Amsterdam, Rome, Berlin and Paris are destinations other users on the same PC have typed in before you. Note that you usually can only buy tickets that start or end in Germany, for example you can buy a ticket from Amsterdam to Berlin, but you cannot buy a ticket from Amsterdam to Warshaw. If you want to buy Amsterdam-Warshaw from www.bahn.de you need to buy two seperate tickets Amsterdam-Berlin and Berlin Warshaw.

There is also a subsection of bahn.de where choices are limited, but this is only to see special international offers and for nighttrains. If you specifically want this section, go to the link above and then try to book, the site will automatically redirect you.

For Zurich-Venice: First go to www.sbb.ch and look at connections only (search connection).

If you pick a connection that does not require a reservation (indicated by a small black R in a square) you can walk to the train station on the day of departure and buy a ticket at the counter.

Good for estimating train prices is www.jizdenka.cz (note that this site is just a tool, it does not get you a ticket!).
