Thanks for the suggestion. Unfortunately it did not help completely.
When we edit the original file with oggCut and then use oggz-validate we
get an error message like the one posted before. Now oggz-sort will fix
the file so oggz-validate doesn't find any errors. However ffmpeg still
produces and error with it:

ffmpeg -i rlang.ogg -ab 56 -ar 22050 -acodec libmp3lame  rlang.flv

This is the same error we had before fixing the file with oggz-sort
Any other suggestions?
