Strange problem playing DVD in WMP/Real/NERO show time

I recently purchased a Samsung S182M DVD burner (my first dvd burner/player on my primary desktop).

After plugging it in, I decided to test it out by watching a DVD on it.

Tried watching movie using Nero Show time… the movie ran choppy sound kept cutting out in short bursts and it finally would get stuck and freeze my computer (until I ejected the DVD).

Attempted to play it in WMP 10 and WMP 11… same issue… sound and video choppy then it freezes until I eject.

Same issue with an old version of Real Player… and VLC.

Finally used Cyberlink POWER DVD player… everything works great, video plays, great sound… and doesnt get stuck.

Whats the problem?
