The "proper" way to do it depends on the source material. If the source material is 24fps film (e.g. most cinematic films) PAL transfers are made by speeding it up about 4% and displaying each film frame for two fields (yeah, audio pitch is increased). If it's material where preserving speed/audio pitch is important, ever 12th frame is displayed for four fields, giving slight "hiccups" in smooth motions. NTSC typically uses 3:2 pulldown. Odd frames are displayed for two fields and even frames are displayed for three fields. It requires very slight slowing down - nowhere near as much as the speed-up for PAL - to get the precise 29.97 frame rate. This produces noticeable motion judder. If the source material was shot at some other frame rate (it could have been native PAL or NTSC) you're pretty much on your own working out how the disc was mastered. But all this is academic - wouldn't it be easier to just get an entertainment system that can play PAL and SECAM as well as NTSC?
