Can't Play DVD

When I put a DVD in the drive, it won't play. I used three applications; NERO, Windows Media and Interactual player. Attached is the error I get with NERO.

Error message reads: Sorry, the folder you have selected is not contain a valid DVD video, SVCD or VCD structure. Please user the "media files" function to browse and play back files from this folder.

 

Tammy981,
The error message means exactly just that. It looks like the DVD you're trying to play isn't properly formatted and structured. Did you do any editing/encoding on this DVD?

 

The DVD is a movie DVD. I tryed several different movies- and they all give the same error.

 

Do you have any other codecs installed aside from the ones that came in with your machine?

 

No, not that I am aware of. I have a basic setup to my laptop with the external Memorex DVD drive (the one that is giving me trouble) and a tethered Cell phone for internet services. Nothing special for video.

 

Tammy is the DVD a store bought DVD or on a burnt Disc ?
