Hi MelodyL.

I was just trying to help, and I did not know about your limitations. I apologize if it came across wrong.

If taking the tower back to the shop is impossible, you may find that your easiest solution is paying the $14.99 for the decoder (even though you don‘t want to).

You may also want to try to download a free trial version of expensive multimedia software like Nero (or another expensive robust brand, the expensive brands sometimes get you better results). The trial versions are free to try for 15 days or more, and you may want to use a trial to see if you can get the DVD to play. This may get you outside of some of the possible compatibility issues, and it may get you the decoder you need to play a DVD. It is even possible that once the decoder is installed, and the free trial version stops working, that the windows player will then be able to play the DVD since the decoder is in place.

Just some ideas, I hope this was a little helpful. God Bless You.
