Noel,
I just closed everything down completely and then brought it back up and everything is working fine like it is supposed to so I'm satisfied that the codecs or lack thereof was the problem and I probably won't need to return to factory defaults. I'm not sure I would know how to get into changing those files anyway, I'm not very computer savvy. I just turn it on and hope everything works. LOL. It usually does so I go on my merry way.
It was nice to know that someone was here to help me out when I needed it. Thanks so much!

Val
