A note about news feed availability
There are periods when news feeds are not available, due to the massive
demand on these public feeds. Repeat Signage caches the last
downloaded feed file and will display this instead. You are advised to
set the refresh to every 30 minutes for public feeds, so if the feed is not
available then it will be collected on the next try. Double click your
RSS control and look at the 'Refresh' tab. The load time of
Repeat Signage presentations can sometimes be delayed whilst it is trying to
collect feed and other information from the Internet during the load.
