from what you're showing me, I take it that I can use the hex codes found in the pronto section of the files and somehow get them sucked into the URC remote? That's awesome. And using your response (for which I thank you.... some folks woulda just said, "try searching") I am now assuming that if I can find a discrete, there's probably a way to get it into the remote. I actually have my Sony receiver on AV1. They ship at AV2 but the harmony wouldn't work that way :)
Anyways... at least now, with your help I can search here in a way I probably wouldn't have thought to search (look for discretes for a URC by searching in Pronto.....) and THEN come and ask how to get them into the remote! ... heheheh
