First you need a program with the right codecs to veiw your movies, you can either install the correct codecs for your player or get VLC media player it is a free download and has all the built in codecs that you need to veiw your files...
Now if you want to burn the file you have to have a program that will convert the file and then burn it, unfortunatley dvd shrink is not one of those, do you have a program such as Nero or Dvdsanta ?????
You will find all your files from Limewire are saved in your shared folder, which is located in your Docs and setts, your foldername...
