I've got my script installed on vu with openvix 5. 1. Everything is working but no picture. I have sky as isp. However I've took it down my friends who has same box and same gift from same source. I plug my box in at his home and boom it works straight away however his isp is first utility. I've taken the sky guard off of my sky account but stil no picture at my home. Any help or direction as to getting a pic step by step guide would be perfect thanks
