WH- The receiver is hooked up to a phone line. the last time we called directv, the firmware update wasn't available. Have you had any updates through a receiver lately?
As far as the picture cutting out- Its dropping out to black. On some channels it does it it constantly every 30 seconds or so and on other channels it does it when a scene changes or when the program cuts to commercial.

Uno- The projector is a DILA unit. We don't think its the projector because it works fine with the DVD player. But I could be wrong. Can you tell me about the problems that you had with the projector that you installed.

Thanks.
Steve
