Comment:

 The following command produces a frame approximately 13 seconds from the
 start:
 {{{
 $ ffmpeg -ss 1 -i AVRO\ Close-up_Ned\ 1_07_08_2010_13_50_05.dvr-ms
 -vframes 1 out.jpg
 }}}
 The following command produces a frame approximately 72 seconds from the
 start:
 {{{
 $ ffmpeg -ss 60 -i AVRO\ Close-up_Ned\ 1_07_08_2010_13_50_05.dvr-ms
 -vframes 1 out.jpg
 }}}
 Seeking backwards by ten seconds with ffplay actually seeks forward a
 little, seeking by 60 seconds forward seeks >70 seconds, seeking by 60
 seconds backwards seeks around 48 seconds backward.
 May be related to the starttime.
