I'm getting back to doing requests finally. I have added support for the Motorola VIP1853 / VIP1903 into Pierogi following the instructions on the links provided (thanks!). (I've plugged it in as "Motorola STB Keyset 2".) This remote is using a "CanalSat" protocol, which is a slightly odd modification of the RC5 protocol. Most likely, I will manage to get some aspect of the protocol wrong on the first try, so if it doesn't work for you, please holler at me. I'm not sure when I'll have the next iteration of Pierogi available, but hopefully soon...
