I just recently picked up comcast and their dvr and am learning all kinds of great stuff. For example, here is the procedure to program 30 second skip to the remote.

  1. Press the “Cable” button at the top of the remote to put it into Cable Box control mode.
  2. Press and hold the “Setup” button until the “Cable” button blinks twice.
  3. Type in the code 994. The “Cable” button will blink twice
  4. Press (do not hold) the “Setup” button
  5. Type in the code 00173 (for 30 second Skip)
  6. Press whatever button you want to map the skip

I just wish I could upgrade the puny drive…
