In an earlier post for this thread I said that I had created one autorun CD but the next one I tried (with different content) was not having it. Well, doh, bugger and all that, it was my fault, not the computers. Who'd have thought it.

On the first "happy" cd the .inf points to index.html.

On the second "unhappy" cd the .inf points to index.html, but the actual file on the disc was called index.htm (no 'L'). Not immediately obvious in WinXP explorer since you don't see the file extension only the type of file, which said "HTML".

All good now though.
