Right, ok but I dont know the difference! It is hard to tweak when you dont know what to look for or what your looking at! So I am continually testing and tweaking following advice from people on here. I understand that reading the instructions is the first thing to do, but the "instructions" are scattered about in a few text files and in no defined order according to the protocol. Personally I find the instructions too vague. So I do have everything working ok but still fighting with garbled audio at times. But in time I will get that fixed.
