This philips pronto .CCF file contains the PIP, SWAP and Position IR codes for remote address 1 through 16 for use with the DVR-921 receiver. As you know, the 921 remote sends only UFH commands to the 921, so it's impossible to teach the pronto the remote control commands from this remote. Fortunately, the 921 recognizes the standard Dish Network IR codes from other remotes. However, the only other Dish Network remote that has these buttons is the 721 remote. I have taught my pronto these buttons from a 721 remote, and present them to you here for use in programming your pronto to control the 921. If you have questions, please ask. These IR codes are for use ONLY with the pronto remote, or can be converted to MX-500 remote commands using the IR Clone tool. For more information, please see www.remotecentral.com Over time, I plan on building an IR code database for addresses 1-16 so that pronto users can use my files here to easily import into their own pronto files from which to alias buttons.
