What is wrong, please help me!

[Bunger]

This is a script written for Linux, but I want to use it in windows,
so I've done the changes I think I need, but it does not work.  I get
these messeges:

Encoding 'test.avi'
Done converting 1 files
Traceback (most recent call last):
  File "C:\Documents and Settings\Bjorn\Desktop\test.py", line 47, in
?
    main(sys.argv[1:])
  File "C:\Documents and Settings\Bjorn\Desktop\test.py", line 43, in
main
    sys.exit(0)
SystemExit: 0

Here is the script, please help me, what is wrong? maybe I have to
change moore code in windows..

#!/bin/env python

import sys
import os
import popen2

INDIR  = "c:\inn"
OUTDIR = "c:\ut"
FINDIR = "c:\ferdig"

ENCPATH = "C:\Nokia\Tools\Nokia_Multimedia_Converter_2_0\MMConverterCon.exe"

def getInFiles():
	files = os.listdir(INDIR)
	
	if len(files) == 0:
		return None
	else:
		fixedList = []
		for file in files:
			fixedList.append(os.path.join(INDIR, file))
		return fixedList

def encodeAndResize(file, store=OUTDIR):	 
	execStr = "%s -i %s -o %s" % (ENCPATH, os.path.basename(file),
os.path.join(store))
	execPip = popen2.Popen3(execStr)
	execPip.wait()
	os.rename(file, os.path.join(FINDIR, os.path.basename(file)))

def main(args):
	
	newFiles = getInFiles()

	if newFiles == None:
		print "Ingen nye filer å konvertere"
		sys.exit(1)
	else:
		for file in newFiles:
			print "Encoding '%s'" % os.path.basename(file)
			encodeAndResize(file)

		print "Done converting %d files" % len(newFiles)
		sys.exit(0)
	

if __name__=="__main__":
	main(sys.argv[1:])
