@ luttge,
Welcome to the Forum.
The simplest way to Convert PAL to NTSC is not attempt the Conversion at all but to use a PlayBack Viewing device that supports both PAL and NTSC video format.
The below Web Link provides information on Converting PAL to NTSC ->

There are numerous other PAL to NTSC conversion guides available. Just use Google Search (
http://www.google.com) for the topic PAL to NTSC.

DVD Region Coding and PAL/NTSC Video Format are two entirely different things. A DVD “Region Free” PlayBack Viewing device does noting to convert PAL to NTSC or NTSC to PAL video formats.
