Hi, I am using a video capture card with four BT878A and one INTEL PCI bridge on it. Each video input channel is connected to one BT878A respectively. I am trying to capture video data from all four channels and compress them to JPEG files at the same time. But sometimes I will get some annoying line noise (as indicated by red circle in the attached file). Does anyone know it's hardware's or software's issue? Is there anyway to avoid this? Thanks! Regards, Kevin
