mbp 3.1 s-video to tv can't choose PAL

Hello all,

I have the apple dvi-i to s-video adapter connecting mbp 3.1 to an old crt tv. The picture is scrambled and black & white.
With system prefs open and windows gathered the tv shows up as a generic vga monitor and there is no option to pick between NTSC and PAL for that screen. I have reset pram, booted in safe mode but nothing changes.
I have tested this tv with a windows pc running xp (without the adaptor) which allows access to the driver and the changing of the refresh rate and yes it works flawlesslyish!.
This setup has worked for me previously in leopard days. Similar problems seemed to associated with the release of snow leopard and was later resolved by the release of 10.6.3. Alas not so for me (on 10.6.5).
Are there any other remedial steps I could take?

Regards Pat

Did you buy the adapter in the States or overseas? There are two different part numbers. The one sold in the U.S. doesn't support PAL timings.

Thanks for your help
I agree that this is what I should expect if it were the wrong adaptor.
It is definitely PAL. it says so on it.
It worked before with this tv but usually needed a reboot to get proper colors etc.
Here is what the edid file in switchresx says (no hints that I recognise here)

Hmm. Yeah, I don't see anything there linking that adapter to PAL or NTSC. Below is the EDID from my U.S. version of that adapter. It always comes up in NTSC timing first, but does allow for PAL (50Hz) selections.

Are you sure yours is an Apple adapter? Usually the name section of the EDID would have APP.
