I started mplayer (mingw64) in cygwin to get the output in an easy form:

[sheldon at sheldon-c2d:/cygdrive/c/mplayer-svn x86_64]$./mplayer.exe tv://
MPlayer SVN-r36500-4.7.3 (C) 2000-2013 MPlayer Team
206 audio & 433 video codecs
getch2: 6 can't get number of input events  [disabling console input]

Playing tv://.

MPlayer interrupted by signal 11 in module: demux_open
- MPlayer crashed by bad usage of CPU/FPU/RAM.
   Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
   disassembly. Details in 
DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
   It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
   gcc version. If you think it's MPlayer's fault, please read
   DOCS/HTML/en/bugreports.html and follow the instructions there. We 
can't and
   won't help unless you provide this information when reporting a 
possible bug.

Using mplayer compiled for cygwin64, mplayer dies a little more gracefully:

[sheldon at sheldon-c2d:~ x86_64]$mplayer tv://
MPlayer SVN-r36496-4.8.2 (C) 2000-2013 MPlayer Team

Playing tv://.

This could be a difference in the mingw runtimes, and/or the compilers.

I have a Hauppauge DVB stick on my Windows 7 computer.
