Yesterday I tried to record Jeopardy as I do every weekday. After 10 minutes of recording I started watching the program, only to find that the sound was fine, but the video was from some other program/channel. I switched to the Guide and clicked on Jeopardy, and the audio and video were both fine. This has happened 3 times in the last year, always when recording Jeopardy.
