While the LD has interlaced frames (30fps; technically 29.97), the BR has progressive frames (24fps; technically 23.976). It’s the LD that needs to be “converted” (de-interlaced back to 24fps). If you’re “ripping” the BR, it’s already progressive and doesn’t need to be “converted”, perhaps just frame-rate specified.
When you’re making a disc, the media will remain at 24fps, but pulldown_flag-ed for the 30fps display.
That should make everything sync perfect.
Otherwise …
