Cable strange signal

[Ender]

Hello!

I have a problem with my cable signal when i catch it with the composite video (you know, the yellow cable ). I know that this error is some interference, but i can't identify. It's no similar to MPEG2 artifacts, it's like a "chess board" effect (see attached file)

Anybody knows whats the hell :-D is it? the same signal, entering by RF doesn't shows...

Thanks

Ender

Silly question........

Is it cross mod with a VCR ????

No, the signal is connected to the TV... ¿there are any well-know effect like this when you connect an VCR?
