The Keyspan DMR documentation says the receiver can detect JVC VCR remotes, but really it can detect more than that. The difficult and tedious part is getting the protocol codes in Keyspan's REM format for the specific remote you want to use. That is what the converter does.
For example, I can take the LIRC configuration for a car stereo remote, run it through the converter, tell the Keyspan DMR application to use the resulting REM file, and the receiver recognizes the new remote.
I make no guarantees that the output of the converter will actually
work with the DMR receiver. I have had success converting some
configurations for Alpine, JVC, Panasonic, Philips, Pioneer, Sanyo,
Sharp, and Sony remotes.
I am using an X10 UR19A universal remote. It is
quite useful with the AUX1 button programmed with code 158, which is an
Onkyo audio system. For that mode, I use X10_UR19A_AUD158.REM.
