Guide Mistake

There's a show entitled "Unspun World" that airs on channel 346 (BBCN) at 01:30 EDT on Saturdays, and then replays a few times over that ensuing weekend.
BBCN often pre-empts these news documentaries when breaking news supercedes. Ergo, I opt to record all those replayed episodes as a back-up to the initial airing.
However, these episodes often replay under the title of "This Week's World" (on the program guide) instead of "Unspun World". It's been like this for months.
Exception: "Unspun World" was on a brief hiatus; during this time, actual "This Week's World" episodes aired in the slots appropriated for them on the program guide.
I enjoy both shows. I've missed one or both several times because of these errors.
Not my receiver. I've reset it, and so have you (DirecTV).
Please help. TIY.
