RCA DTC100 High-Definition/DIRECTV Digital Receiver
Caution: DirecTV no longer updates this receiver
I recently purchased one of these units. It has version 40b of the firmware. DirecTV used to send updates to the firmware twice a day. These downloads ended on 6 Aug 2001. As a result of not having the latest software for the DTC100, I cannot properly view HD material on my InFocus LP350 projector. In researching this problem, I have discovered that the old software also causes incompatibility with other HD displays (Mitsubishi, for example).
