There are about 30 current models with the code, but that's the best one IMO and the easiest to find. If you get the RCA, it needs to be that model exactly. Widely available at sears, best buy, walgreens, radio shack, etc. Your other devices the same codes as your current remote, which would be CBL 0476 for your DVR, IIRC. To find out what other codes you're using, follow the blink back steps in the manual programming instructions in the wiki link in my signature. That's also where you can get instructions for programming the individual advanced codes I posted. If you buy a JP1.3 cable, you can add any codes to your current remote as well as program the RCA from your PC and not have to deal with all those individual codes at all. HERE's
the upgrade file your your device if you get a cable. With a cable you can make that $15 remote behave like a $200 remote.
For a complete list of compatible remotes, follow the Codes link in my signature then search one of the posted codes and click the number under the remote column in the results.
If you post the model number of your DVR, I can give you all the individual function codes for that too. UEI makes your cable remote and the RCA, so they use the same codes. But the RCA is newer and has the latest codes and more of them. It's also learning, has more advanced volume punch thru, device specific macros and more devices.
