I tried that too and can't get it to work. The difference may be that I am trying to get a different remote (for the 6131 PVR) working first before trying it on the UHF/IR remote. I have 2 6131 IR remotes and 1 IR/UHF remote and I'd prefer to get it working on all three the same way so that the interface is consistent. Oh well, I'm stuck with code 667 for a while.
