Happy to say, here in the L.A. market anyhow, we're apparently done with any further channel repack movements due to the FCC incentive auction. As they were really a headache for those like me that use OTA TiVos.
As you have to wait for TiVo/Rovi to catch-up on their end to update the guide which can take weeks sometimes.
Oh, and BTW ....
It's actually only chs. 2-36 that are available for TV broadcasting. As ch. 37 is reserved for radio astronomy and medical telemetry services.
