First off all it's generally not appreciated if you send attachments 
like this to the list.

The shock-issue is something I get here as well when COAX is plugged in, 
just be carefull plugging it in ;) In general it seems te be caused by 
grounding issues.

The lines in your image I see sometimes as well in some programmes, 
especially when I watch programmes on a TFT-monitor. So it might have 
something to do with interlace settings?

Other people might have a better answer to that one though...
