A1200T with s-video converter problem

[Aminator]

I have made an amiga rgb to s-video converter because i want to be able to run programs that use native amiga resolutions thru a tv tuner card.
The problem is that i only get black and white picture. The converter also has a composite out and i can get color thru that but the picture quality is worse.

I'm using pinnacle studio pctv tuner card and my amiga is a pal system and so is the converter. I tried to capture the amiga video to my pc with one of those usb capture devices and i can get color there.
I've tried using supertv and the mediator tv programs but it makes no difference.

I made the converter according to this but as a pal version

Yes, i feel like that's the only reasonable way for my amiga 1200 tower without setting up multiple monitors.
I have tested this also with ati tv wonder, both cards are PAL.

The Indivision scandoubler is expensive and i haven't heard of the ratte switcher and don't know where to get one
