Although the Keyspan Digital Media Remote (DMR) comes with a code map for JVC VCR remotes, remotes from some other brands also work, if you can find out the codes.
To that end, I have created a web page with a script that converts remote control configurations from Linux Infrared Remote Control [LIRC] format to Keyspan DMR format. The script is still young, but I have had some success with configurations for Sony and Pioneer remotes, as well as JVC devices other than VCRs.
I hope someone will find it helpful. I will keep improving it as time allows.
