"Supergirl" airs at 8 Eastern rather than 9 on Dec. 8. My Roamio said 'Record this episode". So I set it to record. Afterward I have a listing for a behind the scenes special. The same special, or a different one, is listed for 9 Eastern Dec. 10. "Batwoman" airs at 8 Eastern Dec. 9. I don't have a season pass so I had to tell it to record anyway. There should be an "Arrow" episode but there's not one listed on Dec. 10. I don't have a season pass for that one. "Black Lightning" and "The Flash" air in their usual slots. I'm not certain whether "Black Lightning" is a part of this.
