Your program is 24FPS and your creating a PAL DVD 25fps?
If so, Frame blending might help.
The occasional glitch, colored line or so in some shots in the premiere sequence can be fixed.
Alter the clip in some way to force it to unrender or have to rebuild.
Can put an emty title over it and render, these will usually fix this stupid, less the pro problem.
Then export to your Mpeg2 Preset for DVD.
Import those files into Encore.
