Spontaneous Deletions from Contour DVR

We had some issues with a previous DVR, so since our most recent replacement, we've been keeping closer track of recordings and capacity.

Last night, we had 293 recordings reported a utilization of 40%. When we checked this morning, the box reported 221 recordings and 29.2% utilization. OVER 60 RECORDINGS DISAPPEARED OVERNIGHT!

There were some deletions of episodes recorded in February and early March, but for the most part, every episode that was recorded Thursday 3/21, Friday 3/23 and Monday 3/25 has disappeared. They do not show up under recently deleted. l the series recordings appear to be recording today (3/26), so far.

Whenever we set a series recording, we always chose "Save  Until Capacity (up to a year). We also always chose to record "new and repeat episodes" and to Keep "All Episodes"

We had issues with pixelation on a previous box, and have not had a recurrence with the new box, however this would seem not to be a hardware issue.

Any thoughts or suggestions would be appreciated.
