Comment (by mjs973):

 I've tried a few experiments with this sample file, and the results are
 just weird. I'm using ffmpeg built from git on June 8.

 Muxing to .mp4 or .ts container gives a file that seems to play correctly
 in ffplay.

 ffmpeg -i 133*.avi -vcodec copy -acodec copy -map 0:0 -map 0:1 out.ts

 The out.avi file created by ffmpeg app does not play correctly in ffplay:
 the video plays slower than it should (maybe 1/3 rate?). Audio seems to be
 playing correctly in ffplay.

 For out.avi, the video timestamps shown by ffprobe look ok, assuming it's
 supposed to be 25 frame/sec video.

 When ffplay is run, the header information read from the out.avi file by
 the avidec demux looks reasonable.

 More investigation is required.
