Chris007, I'm really pleased that you've got to where you want to be. Tenacity pays off and you have provided a wealth of info to people who have followed this thread.

On the modchip question, if you want to play backups, then you have to have a modchip for best results. Most people who have had it done properly are 100% satisfied and don't find a void warranty to be an issue. We take our chances - as you imply.

It will be interesting to see where you go from here.

Best wishes
