Last time I worked with this box, it responded to the just about any of the TWC codes. Scientific Atlanta, AND Motorola. IR worked without any special setup.
BUT, the boxes are a complete POS. Audio out of sync. Constant reboots needed. DVR recordings not happening. Two different customers had them replaced with older boxes that were actually reliable.
I'm Not an engineer, but I play one on TV. My handle is Tweety but I have nothing to do with the organization of similar name. I just had a really big head as a child so folks called me tweety bird.
