In the words of Mr Spock, I don't understand your logic.
Why buy the DVD's in the first place? Either watch them or don't
If you just wanted to get the story outline...go to a web site like
The Internet Movie Database (IMDb) and you'll find episode guide for TV shows and outline for movies.
Do you have a problem with sitting on your backside and resting or are you a hyper person, who feels he doesn't have time for anything....be careful you don't give that impression to others or you'll end up people just avoiding you becuase you don't feel you have the time to talk to them or spend time with them.
Get a nice coffee, some good quality biccies and relax and watch your DVD's....who knowz (God forbid), you may even find you enjoy watching them.
When I want to "switch off" and relax I am enjoying a DVD of "Kath and Kim" too spookily like my own in-laws family!!!! (Then its a horror DVD to me!!!)
