Nero related problem?

I've been getting some very erratic behaviour. For example, DVDs I'd
burned with Nero (both -RW and +RW), and which had played OK, had
later not been recognised. And programs like DeepBurner Pro were
reporting that a disc had insufficient space, when a few minutes
earlier Nero Info had said it was empty.

With help from the video.help forum I've just discovered the basic
cause of this. The suggestion was that my DVD burner (or non-Nero
software) is dependent on a driver file that is not autoloaded at
startup ... that it's only loaded after Nero has been loaded. Ando
after a Win XP reboot (and I was doing lots of those because of
DVD-based system freezes etc), that key file(s) was for some reason no
longer being automatically loaded. (Why is another issue!)

I've just satisfied myself that this was an accurate diagnosis. If I
start Nero Express, choose Burn DVD Video, and then insert the discs
that were being not being recognized, they are now OK - they trigger
autoplay and the DVD is played. And I can now use Nero Info on them
and get a result, instead of just 'No disc inserted'.

But what I can do about fixing this properly please? Is there maybe
something I could re-install to try fixing it? What are possible files
that the driver or non-Nero software is looking for? If I could
incorporate it into my Windows XP startup routine, presumably that
would fix it?

One last thought: I've disabled inCD while I work on my DVD problems.
Could that actually have something to do with this issue?

Do hope some of the experts here can help please.
