Ever figure this issue out? I'm particularly interested since 6170 doesn't even appear for me! I don't know if this is because I already have an HDHR with NBC Sports Philly on Channels DVR, but then again, I get both 846 and 6171 (NBC Sports Philly+). Just entirely curious since NBCSP didn't show up for me in TVE at all!
Getting all of the other NBC RSNs was definitely an unexpected perk! Tried watching Boston with my credentials online and was met with a blackout restriction message (with audio), but Channels played the stream just fine. Woo!
