I have several short videos of a party, made with a Canon digital
camera, and I want to put all of them on SVCD, but I doubt that a
standalone DVD player likes 11024Hz audio. This video is a very old
comic clip with a similar audio format, which shows the same symptoms (I
certainly won't upload the party clips to ftp unless _really_ necessary
;-) (heavy beer usage involved...)
