A warning to users of non-US versions of OS9.

I have been using a G4 AGP graphics (9.0.4) since new. Last year
sometime I
downloaded and installed Itunes1.1 from the Apple site.

After that I started to get infrequent freezes where I had never had them
before. For example, applications using the "Open" function of "Dialog
Services" whilst there was a Kodak Photo CD in the DVD/CD player (normal
format CDs were OK) would cause a freeze. Intermittent freezes when playing
Age of Empires II. It appeared as though it may have been needing to access
the CD at the time......

Anyway I tracked the problem down to either the DVD/CD extension or the DVD
drive itself. So in trying to resolve that I went looking for another DVD
extension. Then I noticed that the active DVD extension had been installed
by iTunes.

Suspicious of iTunes, I then realised that my OS is an "International"
version and that the iTunes that I downoaded was probably US. So I
found an
International iTunes, installed that and freeze problems were solved!

The DVD/CD driver in the International iTunes is 100K or so smaller than the
US one, so they are demonstrably different.

However the real trap is that the "Get Info" on this extension shows that
both International and US versions have the same version number (1.4.3) and
there is no mention of US or International anywhere in the get info box for
the DVD driver. 

Question:-
So how are you supposed to know which extension you have installed? and
therefore whether it is the correct one!

Idle Question 1:-
Why would itunes need to upgrade the DVD extension anyway

Idle question 2:-
Why would the DVD/CD driver need to be different between International and
US anyway? Surely it is the same physical DVD player with ATA interface.

Warning:-
"About this Computer" in OS9.0.4 (well, mine at least) does not mention nor
even hint (no Z anywhere in the version number) that your OS is
International English. I found that by using Apple System Profiler.
