Thx, that is what I was seeing. I now have the model numbers. There are four boxes on this project, one Tivo that looks like it may be an Evolution Digital. I have an IR file for an Evolution UHD box for some reason from a previous project that may work. The other three are boxes Arris DCX860/R4CC/9322's. I see only two IR files in Crestron IR database for Arris which may work. I just have no experience working with Mediacom so just not sure if they have their own proprietary IR for the boxes they provide. Any additional insight from someone with experience with Mediacom cable boxes would be greatly appreciated.
