DVR Chatter

I've started noticing that programs that I have scheduled to record will say, in the schedule, some of this show will be clipped due to scheduling conflict.  However, when they appear, they are  the only shows scheduled to record during that time slot, and there is no possible conflict before or after because there is nothing schedule before or after.  It's very strange. Then when the program records, at the playback screen, it says this show has  been  clipped, but it hasn't.  This wasn't a one time blip either.
