I haven't had any issues with the MX-950 either, especially when used with an MRF-350 or MSC-400. It's RF performance has been no different than any other PC programmable URC remote (they all use the narrow band transmitter these days). In fact, I've been using an MX-950/MRF-350 combo in my home for years now with 100% reliability.
