Comcast DCT6412 DVR mutes on record

June 29, 2005

DCT6412The Motorola DCT6412 hi-def DVR is overall a really nice piece of equipment, as I’m sure many Comcast subscribers have already noticed. The 6412 does however have one slightly perplexing bug to it, namely the muting of audio if the DVR starts a scheduled recording while the player is off. The logic (I’m told) says that if a user has an attached surround receiver that’s left on, and a scheduled recording starts in the middle of the night, the sound coming from the speakers could potentially wake up the whole house, fair enough I can see myself accidentally leaving the receiver on all night from time to time.

The real problem here is that you may not be able to un-mute the DVR until the recording is finished. Let’s say you get home and flip on the DVR to watch a little TV only to have no sound present, ok you say I’ll just “Un-Mute” it, ah ha but what if you erased the factory mute (like I did) in the supplied remote, in favor of your receiver’s mute code into the unit? Not to fear here are the steps to restore the DVR’s mute into any button you like:

1. Press the “Cable” button at the top of the remote.
2. Press and hold the “Setup” button until the “Cable” button blinks twice.
3. Enter 994 into the numpad. The “Cable” button again blinks twice.
4. Hit (Do Not Hold) the “Setup” button
5. Enter in 00141 (for Box Mute)
6. Press whatever button you want “Box Mute” to be.”

    Thanks for this fantastic tip. I just got my 6412 installed last week and I came home in the middle of taping a show tonight when I wanted to watch the baseball game, but the damn thing was muted – and someone had reprogrammed the mute button to the TV (previous customer no doubt)!

    This is a life saver, thanks!

    Great tip. Nice review of the Comcast service and DVR. Another alternative is found on the DVR universal remote control manual – look for the heading of “Changing Volume Lock”. Following step #1 and #2 above, enter 993 and then press VOL – once. The mode key will blink 4 times confirming unlock. This allow you to use the MUTE button under “cable” mode to unmute either the recording in progress or the sound on the second tuner.

    There is also a code for a 30 second skip, same procedure with code 00173.

    A good tip for those not using a universal remote that can accomodate both the audio receivers mute and DVR’s mute buttons. But, if you’re using an HD DVR you have no excuse for not upgrading the remote 😉
