I have a customer who has a Jamo DVR 50. I have learned the codes from the original remote. It worked a little intermittent. So I called Jamo and they said they had an update for the firmware that addressed some IR issues. I have applied the update and now none of the ir codes that I learned work, but the original remote still works fine. I relearned a few codes, still nothing. The codes learn at I believe 35.7Khz. When you look at the waveform it says unknown next to encoding. I was wondering if there are any clean codes out there? Or maybe hex codes I could paste in. Thanks for any help!!
