I've never gotten both feeds before. It is always usually the home team's feed. The two listings may be for regular and HD. However, I've sent the suggestion many times to LP telling them it would be nice to have both feeds available like they do with audio league pass and maybe they took me up on it. But, my guess is it's the regular and HD.
Yeah, you should only get 1 feed. Generally the home teams feed although sometimes thats not the case.
This is a fairly new thing Directv has been trying to add to there sport packages. 2 feeds. It started with the MLB package. Generally, you get the home teams feed if your out of the local market. So I'm guessing tonight that those like me, who are in CA, will get the NJ feed. Unfortunately.
Their is actually 4 listings.
751 Standard feed
751-1 HD Feed
752 Standard feed
752-1 HD Feed
The 751 channels are most likely NJ feeds. While the 752 channels are Bostons. Just going by whose the home team and visitor. Generally, the home teams channel is listed first.
I assume the preseason games aren't free. You must already be subscribed to the NBA league pass. Just a guess though. (unless there is some sort of free preview which they normally do at the start of sport seasons). If its like baseball, and your out of market in both areas (i.e. NJ or Boston), you may be able to pick the feed you want to watch. I've been waiting for this feature and I'm hoping its starting up this year. We'll see.
