Theoretically speaking, if you have a 23.976 fps source and you have to convert to PAL DVD, the correct way to do is:
- convert video to mpeg2 staying at 23.976 fps
- apply pulldown to 25 fps (dgpulldown IS the tool)
- convert audio to ac3/mp2/wav/dts without any speed change
- author to DVD
(that's AVStoDVD path, of course).
Where do your issues come out? Do you have same problem as toology reported?
