Select the TV model (for this I used the 19" TV/DVD Combo LCD), then for remote control type select cable/satellite, then brand select comcast, RC Model select M1057 (may differ by TV model).
The codes should come up 0463 & 10463, because comcast uses a 5 digit code, use the 10463. Although the remote pictured is not the current remote comcast hands out, the code will work on the new remote.
