The cable company periodically tests the "Emergency Alert System". When they do, the screen goes blue and a test notice is displayed for several seconds, accompanied by a weird buzzing sound. Trouble is, this happens when I am recording some show or movie late at night. It happened last night, but fortunately at the end credits (as far as I know). I did see it a few minutes later (Twice), since I set the recorder to run a bit longer than the movie was in case they got the time wrong. Do you think they should publish a schedule for these tests so you know when it's not safe to record? I have erased other programs where the test occured in the middle because I wanted to save the program to DVD.
