[mythtv-users] MythWeather small bug to report

I live in Berlin, Germany and the weather report on MythTV is usually far 
from the reality, especially the forecast seems sometimes pure fantasy.

Some kind of a XMLTV like mechanism would allow me to use a German weather 
website for information (like wetter.msn.de), which are quite accurate. I 
wouldn't mind writing the grabber for that, if the interface was clear.
