For the US locality, the NC-17 rating is level 5, the R rating is level 4.

For the Canada locality, the R rating is level 5, and the 18 rating is level 4. There is no NC-17 rating defined. I don't know the real ratings in Canada, but I would guess it should be the other way around: R = level 4 and 18 = level 5.

It's correct as is.  The Candian R is roughly equal to a US NC-17 and is higher than an 18 rating, which is the same as R.

Thanks. It seems that the Canadians are more restrictive in their ratings compared to the US - if that can be concluded from the very few titles I checked.

All supported formats have built in parental controls.  The most elegant solution woudl be to use the same data as those.  Anyone know of any software that will tell you how a given disc is coded?

For DVDs, that info is stored in the Parental Management Information Table of the VIDEO_TS.IFO. However, it is quite often omitted. Also, the system is designed to provide different levels of access to various parts of the DVD - there doesn't have to be a generic "this DVD is rated X" setting.

Okay, found it.

In DVD Profiler, all per-locality ratings are mapped to an internal rating level (1 - 5). These are stored in the localities.dod, which occassionally gets updated when the Online Profile List (the one that lists all available profiles) gets updated.

[clipped the rest for length]

Thanks for that, very informative post.

Do you know if the mapping can be looked at in the DOD (with, let's say, a text editor, or would I need the SDK)? I wouldlike to chack for myself how the Taiwan and Hong Kong ratings are mapped (especially the former, as I was the one who requested it originally).

The mapping is undocumented and the Plugin API provides no access to it. However, the file structure of localities.dod is not really that complicated. I once posted pseudo code for it in the Plugin Development forum.

For myself, I have written a small VB app that converts the file content into XML. So I can give you the current Taiwan and HK mappings.

EEDIT:
I decided that this warrants its own thread. See here for a complete list of all current mappings for all localities.

And the definition of what you personally define as Adult is held in your copy of dvd profiler
- open tools / options / parental control

That doesn't affect the Online Collection. I have mine set to ignore the Adult genre, but it hides the profile anyway if I change a genre to Adult - as I did with the PG-rated "Princess Bride".

thanks for this. I'm sure that it used to use the internal settings rather than just a blanket in v2.

Although come to think of it that explains why people have their 18 rated films hidden.. 

it's a good job one of us is on the ball!
