For the past couple of months I have had problems with two timers on a 722k. The timers are priority one and two for two shows on the Fox News Channel. They are set to record Monday through Friday. They show they are going to record in the Daily Schedule and are marked in the Channel Guide. A few minutes before the first show is to start recording both disapear from the Daily Schedule and are no longer marked in the Channel Guide for the current day only. They do not record. This typically happens once or twice a week. Wednesday seems to be the most frequent day. The rest of the time they work as they should. I have deleted the timers and recreated them but that didn't help. Has anyone else had this problem? Any ideas on how to fix it?
