DVD or MMP Player do not run at all

Here is one more solution from the list server:

I believe I solved the problem with the DVD player not working.

This is what I did...
I looked through the program folder to see what other DVD players were
installed on the computer. First, I found and deleted a HP DVD player
that came pre-installed on the HP computer (using the add/remove
program utility). When deleting this player, a pop up message warned
that there were 2 files that were shared files. It said that if I
deleted them, some other program might not work. I chose not to delete
them but wrote down the file name and location in case I had to go
back to them - ClAuDRC.dll and Claud.ax in C:\Program\HP\Shared Files\

DVD player still not working.

Second, I found a copy of the InterActual Player on the computer. This
is the program that often asks to load when you try to play a
Hollywood movie on your computer. I searched this in google and found
on Wikipedia that the program sets itself as the default player and
sends information about the computer user back to the company (like
spyware). I deleted this program from the add/remove utility then
found that the folder was still inplace in the programs area (although
it appeared empty). I deleted the folder.

The DVD player still did not work.

Third step...I moved those 2 files mentioned above out of their folder
(I am holding on to them in case some other programs stop working).

DVD PLAYER WORKING!!

I will test the DVD player in my next session with this client This is
set up on the client's computer in another city. I am running
neurofeedback sessions with them using gotomypc and skype with a webcam.

I hope this helps someone else with this problem.
