The problem is that your re-encoded file contains syntax errors.  In 
particular, every 2048 bytes in the file (i.e., at 0x800, 0x1000, 0x1800, 
etc.), the following 4 bytes appear, for no apparent reason:
         00 00 01 E0
This is a MPEG system code that should not be there.

The LIVE.COM MPEG parsing code (correctly) complains about this.  (Media 
players are apparently more forgiving.)

The problem appears to be with "ffmpeg".
