When you say duel feeds, if you mean home and away, then yes they do when the game is carried on both teams RSNs. And they don't necessarily have to be RSNs carried by D*. I get 90-95% of the Blazers games that are televised on CSNNW, an RSN that D* doesn't carry. The only occasions where they don't uplink the games is when there's bandwidth issues (US Open, Masters, etc.). If it's a rare occasion where both teams broadcasts are only on local channels, then they don't uplink either feed. This happened last year in one case when the Blazers (KGW 8) where playing the Lakers (KCAL 9). They NEVER offer LIL on D* LP, but they do on the NBA's online version.
If you're a Lakers fan that subscribes to LP in LA, the away feeds are always blacked out to protect your local broadcast. And if you're a Blazers fan living in Oregon, both feeds are blacked out since they don't carry the local RSN. Ironically, I can see most of the Blazer games broadcast on CSNNW via LP, when a lot of the state of Oregon cannot.
Regarding the Lakers new RSNs, I have no idea how they will handle the Spanish network since it's unprecedented, but I doubt they will offer it on LP. Perhaps they will on the NBA's online version, but who knows?
On a side note, I wish the NBA would do their online version like MLB, offering both home and away feeds, and monthly subscriptions. Some people travel and only need it for a few weeks, rather than an entire season. I also like their two-tier system where you can subscribe to home feeds only, or home and away. MLB is doing a much better job online than the NBA to date. Although, kudos to the NBA for offering their online version for free with LP subscriptions via cable, satellite or telco.
Well based on this, the guy earlier wondering about stu will be glad to know he will get every game except national only ones, and this will be the first year that will happen on lp....
