"unrecognized format" appears when I try and play movie...

I have a gateway laptop.It has a recordable dvd player. It has recorded several dvd's through time.
Now when I try and play a movie I get "unrecognized format."

Does this mean my dvd player is worn out, or could there be a software glich? or is there some simple test I can make to determine where the problem is?

Is it just this one DVD or does this happen with all dvd's?

any and all.

If it is not accepting anything at all I would think that the dvd player/ burner may be going.
