Has anyone succesfully learned the MediaMVP commands into their URC control? Specifically, I dusted off my mothballed MX800, put new batteries in it, and tried to learn the various commands in from my MediaMVP remote. Appeared to learn just fine, but not a single one of the learned commands worked.

First I thought it was one of those weird alternating IR code thingeys i've read about here/there, but given that not a single command learned fine, and that i've previously been able to learn into this remote, I don't think the MX800 is the problem.

Thanks in advance for any assistance.
