FZ200 video question
Only if you want to watch in a TV directly from camera but I guess most modern TV will have both systems, NTSC and (local) PAL. In several countries PALis used only for broadcast air TV and else media as DVD or gaming consoles are NTSC. Unless Europe with PAL-B or Japan with NTSC-J all other countries use sub types of PAL that are different to EUROPEAN PAL-B. That's why every else is backwarded to NTSC. But I don't know how exactly is in China.
Every thing involving a computer should work and this includes uploading to internet .
