dvr no longer buffers during watching a recording plus dvr stops buffering after a few hours

Good afternoon.

I am experiencing the following since Dec 2025

When I wake up, or go away for more than a few hours, I no longer can rewind 60 minutes like I used to be able to do.  Sometimes there is a screen saver.  I have power saver disabled and messed around with CEC.

I also can no longer rewind live TV after completing watching VOD or DVR recording.  I could leave my TV on a specific channel, watch a DVR recording, then come back and be able to rewind up to 60 minutes.  This no longer works.

Both of these worked until Dec 2025.

I have replaced the DVR and that did not help.

Has there been a change on the X1 platform to disable these really good capabilities?
