Repeat of live short segments

I am seeing a somewhat rare repeat of a segment when viewing a live program, one repeated segment and then back to normal. It seems to be restricted to one local RF channel. I almost never record from that RF channel.

This started to happen sometime after the beginning of 2024. Almost perfect performance for a couple of years before this began.

I have not changed any equipment. The Tablo Lite is viewed thru a Netgear Nighthawk router to a Roku Ultra using ethernet cables.

Not a serious problem, more of a curiosity.

Anyone else seeing this issue?
