Are you a JP1 user? If so, there's a file for the LG DV7832 upconversion model here: [Link: hifi-remote.com]
and the LG FL-R888K - Karaoke-VCD model here: [Link: hifi-remote.com]
The signal in the first file matches DVD codes: 0591, 0741 and 0869.
The signal in the second file doesn't match any DVD codes that I know of, so maybe it matches the DVD/1906 code that Edmund mentioned.
Just FYI, the DVD/0591 can be found in almost all of the recent OFA and RS remotes, probably including yours, but you didn't mention which remote you are using, so this is just speculation.
