What are your export settings?
Audio coded: uncompressed
Channels : stereo
sample type: 16bit
Video codec: DV PAL
ASPECT: D1/DV PAL(1.0940)
(CHECKED): use max. render quality
use frame blending
(not checked) render at max. depth
I hope this is helpful
Well, I'm not seeing anything obvious here.
How are you playing back the export?
With windows media player
Another thing... Some audios are mono, some are stereo... could that have anything to do??
Try downloading, installing and using VLC for playback. Report back.
