Forcing an EPG update in SageTV

Here's an easy one for SageTV users: if you somehow mung up your EPG so badly that it thinks that your last update was somewhere in the future and your next one really IS in the future, you can force an update by going to "Setup -> Setup Video Sources" and clicking on your video source (hint: it'll start with a number). Click on your source and then "Channel Setup". Then scroll down and click on one of the channels with the green ball on the left. (Hint: the green ball should go away.) Click on it again, so that the green ball comes back.

Now go check your SageTV homepage (if you have the web interface installed). The datestamp for the "Last EPG Update" should be right about when you clicked on the channel button the second time. (Wiki notes here.)
