encore should ask you when you start a new project weather you want it to be NTSC or PAL format. from that point on, that project will be whatever format you chose. I am not sure that you can change it afterwards. never really had to mess with changing it afterwards since I am NTSC in the US. So I never have needed to use PAL since all it does is cause problems over here where only the newer DVD players play PAL format movies.
