help needed with svideo on 130XE

Hi all,

I'm having some issues with a 130XE and a svideo cable.

When I use the same cable on my 800XL (svideo mod) and on the 800XLF, I have a good image.

But on 'all' my XE's (130XE and 800XE) I have give a distorted image.

So, my TV is ok, the cable should be ok.
But I can't believe all my XE's are faulty.

Does anyone have an idea on this one?
I've included a picture.
