I've read reports where the new firmware for the DTC-100 was sent every day at 4:30PM and 5:00AM. I've been at 2.37 since August 9th when I first signed up with DirecTV. I finally spoke with someone knowledgeable at DirecTV. I was told the upgrade schedule for the DTC-100 ended on January 4th. There are other upgrades going on for various TIVO units but nothing more for the DTC-100.
