Anyone

My TV system is PAL, so all my works are in PAL format. But i need to make a DVD Video for an United States (NTSC) client.
What are the steps i should follow to make the DVD? My movie is in PAL system (720x576, 25 fps). Do i need to encode it in NTSC format (720x480, 29,97 fps)? If i need so, i know that the image will have some jitter, some jumps !?

I will apreciate an answer ASAP. Thanks!!
