| I haven't had this before to my knowledge. I'm converting AVC and AAC to Xvid and WAV through Vdub and the resulting audio that is produced has this metallic kind of fast stutter effect that starts on each batched processed video at exactly 3 seconds and lasts for about a half of a second. It's pretty bad if your talking when that effect happens, lol. Anyone know what causes this? |

| Interesting. If I use direct stream copy the audio gets saved out as a wav file anyway and doesn't have this stutter effect or if I downsample from 48K to 44K I don't get that effect. Hmmm, don't know what this means? Correction - if I process them singularly through direct stream copy or downsampled to 44K I don't get the stutter effect but when I batch process with the audio at any sampling rate, the stutter can be minor or extreme. |

| Sounds like your AAC audio decoder has a seek bug. What are you using? |

| For the audio I would say that I'm using FFDshow. Looking in the audio decoder section I'm seeing libavcodec enabled for AAC. For the video CoreAVC is being used. Usually when I load a video in I'll see icons for like FFDshow and such but nothing shows now? |

| When I play the original files back in MPC-HC they play fine. |
