Cannot get it to work. Can you add international weather locations?
Yes, below is an excerpt from the nitoTV wiki on how to do this.
...you can go to weather.com, type in your location and after you select from the list that appears the location id will part of the resulting url. For instance I searched for "Amsterdam" and chose the first option "Amsterdam, Netherlands". The resulting URLhttp://www.weather.com/outlook/travel/businesstraveler/local/NLXX0002?from=search_city has the location ID embedded. NLXX0002 is the pertinent ID. If you put that ID in (for whatever city you choose) that SHOULD give you the proper weather report for your location.
