By following these steps, you can reprogram a button on your silver Comcast television remote control (made by Motorola), so when you press the button, it skips forward 30 seconds. [See Update 2 below for X1/XR2 remote]

Obviously, this would be very useful for skipping over commercials, which is probably why it wasn't programmed in the first time.

Comcast remote controlStep-by-step:

  1. Choose an unused or unneeded button on the silver remote to become the new 30-second skip command. A good choice is the ‘A / Lock’ button since many users don’t need that function.
  2. Press the Cable button at the top of the remote to put it into Cable Box control mode.
  3. Press and hold the Setup button until the “Cable” button blinks twice.
  4. Type in the code 994. The “Cable” button will blink twice.
  5. Press (do not hold) the Setup button.
  6. Type in the code 00173.
  7. Press the A/Lock button.

That's it!  Now anytime you press the A/Lock button when watching a recording, you will skip ahead 30 seconds.

These hacking instructions work on the Motorola HD DVR DTC6412 and the Comcast On Demand Remote (Comcast URC-106XXXXX Silver Remote).

UPDATE: This does NOT seem to work with the newer dark gray remotes that say "xfinity" towards the bottom. For these newer remotes, try these steps:

  1. Choose an unused or unneeded button on the remote to become the new 30-second skip command. A good choice is the ‘A / Lock’ button since many users don’t need that function.
  2. Press the AUX button at the top of the remote.
  3. Press and hold the Setup button until the “AUX” button blinks twice.
  4. Type in the code 01376. The “AUX” button will blink twice.
  5. Press the AUX button again.
  6. Press and hold the Setup button again until the"AUX" button again blinks twice.
  7. Type in the code 994. The "AUX button will again blink twice.
  8. Press (do not hold) the Setup button.
  9. Type in the code 00173.
  10. Press the CABLE button.
  11. Press the A/Lock button.

xfinity XR2 remote for X1UPDATE 2: The Xfinity X1 cable box remote control XR2 can be programmed, but it requires completely different steps. These steps will program a 30-second forward skip into the Page UP button:

  1. Press the EXIT button three times in a row.
  2. Type in 0030 with the number keys.
  3. To return the button to the default 5-minute button, follow the same steps, but enter 0500 instead (the 4-digit code is the skip time in seconds).
