Thanks for all your help Larry, much appreciated. I've redownloaded both discs from Roxio for MyDVD 10 and run them both and seem to be getting somewhere, well a step further at least. When I run the content disc for MyDVD10 it tells me that I need to install Easy Media Creator 10 which will cost me an extra £49 (which is not a problem, would have been nicer if I knew this before purchase though).
Does that sound right, do I need to buy Easy media Creator 10 in order run MyDVD 10 which does prety much the same thing? Maybe I just need Creator? You're really helpful Larry, and I'm very grateful for your assistance and advise, so thanks!
