I created a remote a month or so ago with all standard STB functions and custom graphics for 0710. The designObj you want to look at is 2427 (mnuSatelliteCableBox). I'd be happy to share mine if someone wants to tell me how. As a caveat, I didn't create a new skin for that version, I simply changed/added designObjs in the Basic skin; I think the only already existing designObjs other than 2427 that are affected skin-wide are 2440 (grpLightControl) and 2288 (grpVolControls) since I added new designObjs for the rest.
Anyway, here's a screen in case anyone is interested. The buttons turn yellow when selected so you know when you've pressed something.http://img13.imageshack.us/img13/8226/mnusatellitecablebox.png
It's kinda hodgepodge but it *was* my first HADesigner attempt. Oh yeah, this was before I added lighting so the light control isn't on this one, but the actual designObjs are changed and just need to be re-added to 2427. I have to swap out my HD to get to 0710 db's if anyone actually wants the designObjs, but I have the images handy in both png and psd formats if you want to do your own thing with them.
