I'm posting this on behalf a friend who doesn't have internet access.

Hi, I've been using my A1000 for about 3 years. 
It runs all PAL software and Krammdenn SI also says that its video mode is PAL,
power supply frequency 50 Hz, vertical blanking 50 Hz.
Currently I've got a project such that I have to record my A1000 output to
video. I connected a video directly to A1000 composite output, it doesn't give
me a colour output (only black and white). A friend told me to use A500 RF mod,
I have tried it, and it still give me a BW output.
Then I tried to connect an NTSC colour monitor, voila, it gives me a colour
output. So it seems it has an NTSC colour encoding scheme even it runs all
PAL sofware perfectly. I have traced this problem, may be it is because
the A500 RF modulator uses the composite sync which is at NTSC frequency.
Is there any way to overcome this problem ?
Will genlock help to solve this problem ? (I can afford to have a cheap
genlock if neccessary,  but I have to be able to record in PAL video).
FYI, my A1000 is not the international (single board) version but the one 
with pal daugtherboard.

Thanks for your info.
