DVD player refusing to play in 10.3.9

Can a drive with specs

 Model:    MATSHITA CD-RW CW-8123
 Revision: CA0T
 Drive Type:   CD-RW/DVD-ROM
 Disc Burning: Apple Supported/Shipped

be expected to play a French film on a commercial DVD?

The specs are for the CD/DVD that came in a G4 PowerBook with 10.3, now
at 10.3.9.

When I insert the DVD I can see that there is an audio folder and a
video folder on the disk (which means it's being looked at as data).

But the DVD Player promptly terminates when I launch it.

I would be grateful for any pointers -- software, limits to region
switching ... thanks

(In the normal way of things we rely on a cheap all-region DVD player
with a scart socket to the TV set)

Normal behaviour for a drive that is region locked to a different
region is a popup saying just that, so there's something wrong
happening here.

Try VLC. That won't get past a firmware locked to the wrong region,
but reads any DVD region and won't check in software.

Although

implies that actually it will. Try and see!

Thanks for the recommendations.  What an amazing website.  Noted for
future exploration (since the problem has in some way cleared itself).

France uses the same region encoding as the UK, so I doubt it's a
region issue. It's more likely to be a complex copy-protection issue
if it's a recent DVD< or a encoding issue if it's an early one. Does
Console give any clues?

Console had recorded DVD Player crashing three times on Thread 0, each
time reporting

   Exception:  EXC_BAD_ACCESS (0x0001)
   Codes:      KERN_PROTECTION_FAILURE (0x0002) at 0x00000024

Which looks alarming to me!

However, the more promising news is that having powered down for other
reasons, I've just found that DVD Player is no longer crashing at launch
with the same DVD present.

Thank you for your help

No, that's a pretty common sort of crash - the kernel is stopping the
app accessing protected memory. DVD Player shouldn't be doing that.

Cool. I wonder what the problem was.

Cheers,

Sorry to be a bit pedantic, but have you used the Mac to play DVDs
before or done anything to necessitate a OSX re-install?

I had a problem with my MBP refusing to play DVDs after a drive
replacement and it turned out that it was set in System Preferences to
do nothing with DVDs. Try that.

Also, as other people have suggested, it could be some bonkers region
switching, though France is the same region as UK - however, that's
assuming you're from the UK or Europe even....

Like Jaimie said, if all else fails I'd be inclined to try VLC (it's
Freeware). That usually plays anything I find.

It's my wife's PowerBook, which has in its time met most of the other 7
Macs run by my children and grandchildren.  At some time it's had its
region reset to Region 1 to watch DVDs from the USA, and has 4 resets
left.  It's only had two major bouts of OS changes, once when we had the
local experts in set us up with wifi and ethernet and broadband, and
once when I finally got round to getting a machine that _required_ OSX
and moved the PBook to 10.3.9 while I was going to 10.4.9 and later.

That bit was OK.

I'm persuaded that I ought to have VLC around

Thanks
