I doubt the Sanwa Rx is the issue. These things just put out a PWM pulse and the encoder just puts the PWM from the different channels into one single, serial data stream. The problem is probably getting/figuring out what switch/know/slider your channel 5 is on..usually the gear switch...and then you may have to adjust the end points of the switch to get it to activate the menu. Without a doubt, this is probably the worst part in getting the system set up. Once done the rest is much easier. The FTDI connection is the easiest way to do it.
As for the radio selection type. The DOSD is trying to figure out what type of radio it's connected to by the type of signals it's getting. I was using a MPX Evo with a Spektrum Rf module on mine at first. I ended up having to manually set my radio type to 'custom' to keep the DOSD from reassigning some of my 'basic flight control' input assignments.
In all, I think you're just going through the learning curve/pains we've all dealt with when learning how to initialize/setup an OSD. These things have to be made to work with as many radios as possible so there are little nuances that have to be worked around to get them to work with your particular system. Sorry to hear your frustration, but I'm sure you'll be very happy with the DOSD once you got things going. I know I LOVE mine and wouldn't trade it for anyone elses...but I would sell it for one, no, two million U.S. dollars!!!!
Last thing. No the DOSD is not perfect...nor is anyone else's system. Feel free to ask questions and advice here as there's lots of folks willing to help out.
