I think you have manged to cover it quite well sir, it is me who has the issue with understanding tech issues. I'm just hoping that the cable is not restricted to one computer use or I will have to take the plunge a buy it myself.It can become frustrating especially if it is a new subject then to have answers coming from all directions confusing you more. Just be patient and hopefully David can confirm to you exactly what he has cable wise. When it arrives you can ask again if you need any more clarification but think I have covered it now.
