I recently bought a Philips HTS3565D home theater system and have a comcast Motorola DCH3416 DVR box. When ever I turn on the cable box the home theater system turns on too, yet i did not program it to the remote. It appears to have the same IR codes as the DVR. When ever I block the IR port on the home theater system, the box wont turn on when turning on the DVR. I have no idea how to fix this and any help would be great!
