Python and audio conversion

#! /usr/bin/env python
import sys, os
from subprocess import Popen

# Mp3 ==> Wav
file_in = raw_input("Mp3 file:")
cmd1 = "mpg321 -q -w in.wav " + file_in

retcode = Popen(cmd1, shell=True).wait()
if retcode != 0:
    print 'Mp3 ==> Wav failed.'

# Wav ==> Ogg
# ==>
opt = raw_input("1)Quality Mode" +
                "2)Bitrate mode\n")

if opt == 1:
    quality = raw_input("Select quality \n\n 1)Low \n\n 3)Normal " +
                        "\n\n 5)Higth\n")
    cmd2 = "oggenc -q " + quality + " in.wav"
    retcode = Popen(cmd2, shell=True).wait()
    if retcode != 0:
        print 'Wav ==> Ogg failed.'
elif opt == 2:
    min_br = raw_input("Select minimum bitrate:")
    max_br = raw_input("Select maximum bitrate:")
    cmd2 = "oggenc -m " + min_br +" -M " + max_br + " in.wav"
    retcode = Popen(cmd2, shell=True).wait()
    if retcode != 0:
        print 'Wav ==> Ogg failed.'

Arrived to the ==> line, the program exits...why???
