* .mov files with uncompressed audio can't be correctly processed 

because of the sample_size == 1 and MINOLTA hack relying on
      the information. So in a way, it's a hack of a hack.

      btw, if somebody knows why in the world even Apple's software
      thinks that for PCM 16bit sample_size == 1 please let me know.
      It clearly isn't documented that way.
