This file is based on the CCF that I developed for my TSU2000. It served me well for several years. This colorized version uses graphics that I downloaded from RemoteCentral (thanks guys). The programming logic is solid and makes the file very very easy to understand and use on your remote. It uses discrete codes for all devices except for the Motorola cablebox (I leave it on all the time). All of my CDs are organized alphabetically and accessible on the 400 CD changer. Favorite TV stations are also accessible by clicking station logos. DVD, TV, Cablebox, DVR, and Receiver menus are easily accessible. In short this is a very user-friendly file!
