avconv log

I am using avconv (libav-11.3-win64) to convert my DV videos. 

The problem is that I don't get the full length video
in the output file. The length of input file is 06:30 min, but that of
output file is only 4:57 min (7426 frames). 
There is no problem of space on my disk (110.710.976.512 bytes free). 
I've tried with multiple input files, of various length (> 06:00) and the
output file always stops at 4:57 min. 
I've tried also different output codecs (dvvideo, x264) but the output file
always stops at 4:57 min.

Here is a simple example converting from dv-avi to dv-raw using the native
dvvideo codec:

avconv  -v 9 -loglevel 99 -i DV-AVI-TYPE1.avi -target pal-dv DV-DIF.dv

Input #0, avi, from 'DV-AVI-TYPE1.avi':
  Duration: 00:06:30.00, start: 0.000000, bitrate: N/A
    Stream #0.0, 1, 1/25: Video: dvvideo, yuv420p, 720x576, 0/1, 28800 kb/s,
PAR 16:15 DAR 4:3, 25 fps, 25 tbn
    Stream #0.1, 1, 1/30000: Audio: pcm_s16le, 48000 Hz, stereo, s16, 1536 kb/s


No more output streams to write to, finishing.
