 Summary of the bug:
 I remultiplex an input file which is an MPEG2-PS with mpeg2video and mp2
 audio.  The video is interlaced with frame rate 25 (= PAL).
 The output is avi file, with same vcodec and acodec.
 The output video has double the frame rate (=50), and each frame appears
 twice when AVI file is opened with NLE.
 How to reproduce:
 {{{
 % ffmpeg -i input.mpg -c:v copy -c:a copy -f avi output.avi
 ffmpeg version  N-55721-gc443689
 built on  Aug 22 2013 19:06:24 with gcc 4.7.3 (GCC)
 }}}
 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
