Excessive ads on dvr recordings

In the run-up to the 3rd season of The Ark, I've been playing the previous programs, saved on my X1 DVR. They have become unwatchable! 

In the past, saved recordings have matched the broadcast that was recorded, including its ads. (So, they had political ads for elections in the past.) Now, current ads are being inserted. Were these mere replacements for the recorded ads, that would be no big deal. However,

I'm getting less than 10 min. of program and then a block of ads (up to 10 ads). In at least one case, when I carefully monitored the time, I got 10 ads, then 7 min. of program, and then 5 more ads.

What's going on?
