I've converted at a pal avi into ntsc dvd and converted the mp3 audio to ac3(192k) using Besweet(pal>ntsc). But the ac3 has pops and clicks. I've tried different media players and my dvd player and I still have these pops. Any help would be great.

EDIT: So I tried encoding it with WAV to AC3 Encoder instead of besweet and did not get pops and clicks.
