I did a search on NBA, then chose "NBA Basketball" from the search results. I had already hit record on the Clippers @Spurs game. I then wanted to selectively add each playoff game. Once I added the first, I could not add any more. I guess all the "First Round: Teams TBA" games are regarded as the same episode. For example, I can't record the Sunday game. The UI tells me the game is already queued for Saturday (but that's a different game).
OK, so that didn't work. I next tried a league pass. That would also include the Clippers/Spurs game, but that's fine, I want that game anyway. So, I added the league pass, but I still only get the first playoff game and can't add any more. See attached photo. Even if this is due to guide data, it would be nice to have a straightforward way to force an epsidode recording even if the DVR thinks the show is already queued.
