But the Bash call worked?

cmd = 'vlc http://"HOST":PORT -I dummy --sout
\'#duplicate{dst="transcode{vb=400}:std{access=file,mux=avi,dst=testing.avi}",dst="std{access=http,mux=mpjpeg,dst=127.0.0.1:11300}"}\''

print '\n'.join(shlex.split(cmd))   # shlex.split parses like the shell

Output:

vlc
http://HOST:PORT
-I
dummy
--sout
#duplicate{dst="transcode{vb=400}:std{access=file,mux=avi,dst=testing.avi}",dst="std{access=http,mux=mpjpeg,dst=127.0.0.1:11300}"}
