Comment (by ramitbhalla):

 Sure, the original video is 5GB, I've cut out a 100MB and uploaded it
 here.

 http://www.mediafire.com/?8bfooipkdf1e56l

 The complete original command I'm using is (converting to divx):

 {{{
 ffmpeg -async 1 -threads 0 -drc_scale 0.8 -y -i test-audio-broken.ts -ss 3
 -vf yadif=0:-1,hqdn3d,crop=1280:720:0:0,scale=720:400 -vcodec mpeg4 -vtag
 xvid -b 1800000 -f avi -flags +mv4+aic -g 300 -dts_delta_threshold 0
 -acodec ac3 -ab 256k -ac 2 test.avi
 }}}


 However the problem can be replicated (and is actually aggrevated) using:

 {{{
 ffmpeg -i test-audio-broken.ts -vcodec mpeg4 -vtag xvid -b 1800000 -acodec
 ac3 -ab 256k test.avi
 }}}


 basic output:
