I am in Europe. There is a PAL system, not NTSC. In version 6 I used only one option. Interlaced or one field and everything was OK. When I tryed used both field, signal was not so stable(bad quality, something like flickering?). So I used only one option. In version 7 default(I think) is option = both field. But If It is possible I want to changed it. Thats my problem.
