I just noticed that the series link I have on my HR20-700 for Costas Now is not picking up this particular episode which airs tomorrow on HBO.
As I looked into it, it appears they have the title listed as I have it in the title so I'm guessing my DVR thinks it is a different program.
Apparently this special comes from when Hank Aaron and Willy Mays were on the last Costas Now in July. They were on live for the last 15 minutes of the show. After the show went off the air they kept talking with the cameras rolling and now HBO is running what we didn't see that night.
Sorry if this is in the wrong area, I wasn't sure if this problem went beyond DirecTV or not.
