looks like the program prints some output to stderr, and some to stdout.
possible solutions:
1) if your shell supports it, add "2>&1" to the end of the command line,
to send all stderr output to stdout. random google link:
http://www.zeitfenster.de/bash/Bash-...o-HOWTO-3.html
2) use os.popen4 to get a file handle representing both streams. see:
