Just replaced my ageing stereo separates (20 years plus) with two Marantz units - a SD4050 dual cassette and an SR4400 surround receiver. Cassette deck works fine, but I'm having a lot of problems with the amp. I now have a fine collection of remotes and want to teach the one for the Marantz (which is a RC5400SR - not one with an LCD) how to control what some of the others do. However, the method seems awfully complicated (press this, press that, count the number of times the LED flashes - goodness sake!) and so far I've had no luck getting it to control anything but the SR4400. Has anyone out there, by any chance, done this? Is there a way of entering the codes straight into the remote? There are lists of codes on a number of websites. BTW if anyone is considering the SR4400, it has the worst set of speaker binding posts I've ever encountered. Chris.
