3-4 secs audio pauses

[DaMan]

I am been getting continual audio pauses (3-4 secs intervals) for the duration of the movie.
TMPGEnc 2.57 Plus Encoding logistics...

DVD2AVI: Forced Films, downsample 48 KHz to 44.1 KHz
VideoCD : NTSC 23.976 fps FILM
CQ_VBR: 300-1800 Padding, Quality 75
Stream Type: MPEG1 VideoCD (Non-Standard)
Audio: 224 kbits, Stereo

Can anyone shed some light?

Thanks in advance...:confused:
