It works to restore disputed channels and local channels that are not on the satellites. Guides are dependent on D* to update there data base. Lcc’s seem to be hard to get unless there is a local dispute.
KUSA in Denver is showing the dispute screen. Being the cheep SOB that I am, I called ‘D and after a 15 wait on hold, I complained. The rep looked at my account and gave a $20 one time credit. Gotta be nice when you call or they can be just unmoving and useless.
Just as soon as you loose your channels, call 'D and get an LCC. Did that last dispute with a different local and now when there is an issue, I just switch my favorites list from the sat to OTA.
