I have a ReplayTV and like Slack, I had to remap most of the keys to get it to be close to the original. Once I ran out of buttons (and the Harmony has so few compared to the ReplayTV remote), I found that adding many of the ReplayTV's options to the menus works even better.

Right now I would say I can do 90% of the things I could do with my origninal ReplayTV remote. I just have to figure out a few more things and I will be done, but I don't think it is ready for the general public (the rest of the family) yet.

Once I get some help screens (via ADDMENU), I will have something to be really proud of.

I will finally be happy when I can hand the remote to someone who doesn't know my setup, and they can watch something on their own. The day that happens is the day I can say I have finished "playing" with my Harmony.
