There's not a way that I'm aware of. Often times, the cable/sat boxes have their own code banks for various televisions, but the option is ultimately up to the cable/sat company to program the codes for their remotes. The TV menu doesn't have any options that would change that.
We just had a Rogers technician here fixing our digital cable....he said there is a way to change the settings on our tv or remote so that when we turn up the volume it scrolls up smoothly to increase or decrease the volume so we don't have to keep pressing the volume to change the volume. Is there a way? We use the remote from the digital box. We have a Samsung LN40A450
