Lots of people have posted that once they are in full screen playing a video that they have to hit the green media center button to get out of the video and go back into SecondRun.tv from the beginnnig... JUST USE THE CANCEL or CLEAR BUTTON ON YOUR REMOTE! Im pretty sure ALL Media Center remotes have this button... basically its the same as pressing the ESCAPE key (which is how you exit full screen using the keyboard normally)... then you can just hit the back button to go back to the previous screen!
