Hi David, Tony,
Thanks for suggestions, having logged on again today, all appears well.
Strange thing was that the entire section "Rio Advanced Digital Audio Center" wasn't visible on the main index page, even after going back and forth a couple of times and re-loading the page. Perhaps there's a bug which David suffered also? This on a Win ME PC with IE 5.5 BTW. Anyway, will keep David's suggestion in mind next time I loose this section again.
On to the subject itself of copy protected CDs, here's a useful link which tells you what CDs are "protected", or more accurately put, corrupted.

Here's one specifically for the UK, Europe:

Any of the other testers have experience with this?
I'll edit & repost appropriate sections in the "Rio Advanced Digital Audio Center"s Technical forum
