My 6000 is typically left on an OTA channel when it gets shut off at night. It's been a very busy few weeks, and there's been times when it hasn't been tuned to a Dish channel for a while. I sub to AEP, LP and HD-Pak but couldn't see the first two games. Intentionally, I left the receiver on channel 101 before turning it off the last few nights. Tonight, I see that the HD-NBA is now showing up in my "Past Purchases" screen. Must be that they are sending out the authorizations for a short period of time, and if your receiver is off and tuned to an OTA channel, it doesn't get the authorization when it is sent out.
