Most of my series recordings for the next two weeks have been knocked out, had to put them in manually. I have dcx3510 model. Also have a second machine with just a couple series recordings, and they also were knocked out.  All the shows are showing "new" in the quide, and I have plenty of space left.  Rebooted the box but it didn't help, as new days are added in schedule they are still not showing to record.
