iTunes and ROKR mobile phone - found a way of making it all work !fixed!
What I quickly realised is that iTunes on the Motorola does not work as if it were a Window application and so is impossible to manipulate. Hence the reason it requires a specific version of iTunes on the PC to make the whole thing work.
In short. Newer versions of iTunes installed on a PC do not comply with the rules required by iTunes on your Motorola.
So the answer is to have two versions of iTunes on my Windows PC. One version for my oldest daughter's iPod and another one for my youngest daughter's Motorola. This means that there are two seperate iTune libraries in the My Music folder. This is a bit inconvenient but as my daughters have totally different music tastes it is not a big problem for me. My daughters can share music files by using Windows to copy files between the two different libraries.
To see how I got this far read the next posting where I have explained
