I believe in order to get NBATV Ch#402 you must have AEP or subscribe to a Multi Sports Package.
---------------------------------
Also,
In order to get NBATV Ch# 562... which is the same as #402... you must subscribe to NBA League Pass.
What sucks about this is the fact that if you order League Pass... and do not have AEP... you only receive NBATV on Channel #562. This channel does not have the EPG data. Therefore the only way to record anything, original programming etc... is to do a manual timer.
(They will not give you channel #402 if you subscribe to NBA League Pass, unless you have AEP or Multi Sports Package)
Nothing like paying extra to get NBA League Pass and having to look through the guide on a different channel # to see what is on!
It really sucks!
