Yeah it's always much easier to have someone who knows what they're talking about help you then spend endless hours trying to find it on google. I had a similar problem and I spent 3 days trying to figure it out until my neighbour took a look at it for 2 seconds and gave me the right cables.
Stop being such a grouch Sebulo.
Also, Serduszko, you don't need to be so rude... gawsh.
I remember years ago you could buy an adapter box that could do what you're asking, but I can't seem to find it anywhere now.(It's probably discontinued now) So then,that cable you posted will probably be your best bet.
Serduszko, I bought this years ago and want to say that, though the picture is far from perfect, it gets the job done. It just took some tinkering to get the picture centered on my TV. But of course, you already said you'd buy it, so I guess this is just reinforcement ^_^
