Many thanks Ric. Well, it's a relief to know that it's VLC that's flawed in that respect and not just something I've done wrong in burning etc.
I've tried again with WMP, following the selection of "All Music", as you indicated and this time I was able to see all the tracks which I'd burned, although not displayed in a neat list as yours are. Also, when I've pressed 'Play' they have been played in a totally random order, which is no good because they're classical tracks which go together, for example three movements of a symphony but WMP delivers maybe the second movement first, then goes maybe to another composer's work and then comes back and plays maybe the first movement of composer A. But I guess I'll just have to experiment with how I burn them. I'm guessing it's best to do them in large batches, which, hopefully, will stay together and in order when played. Anyway, thanks again for all your work. I'll keep you posted on how I get on.
In answer to your last post: I actually don't have a DVD player.
