I couldn't find any long S Vieo cable in the stores the longest was only 3 metres. Apperently S Video is too old for the stores to carry because no one uses it anymore.
A couple of days later I noticed some exterior telephone cable in the garbage room at work, I check there often, it is amazing the things people trow out. I grabbed the cable and now have 7 metres of 8 wire phone cable. Going back to the store I bought that short SV cable.
Step 1: Materials list:
Silicone rubber putty, and
Uncured rubber tape.
You can use Electritian's tape instead of the last two items.
