I like to buy TV shows on DVD because of the following reasons. 1. Un-Edited and complete. 2. No annoying logos on the screen. 3. No annoying talk overs over the end credits. 4. No annoying squezzing the image to promote what is on 30 seconds later. 5. In-tact opening theme songs. Some TV stations have edited out the opening theme songs and just run the show with the credits superimposed over the show. Of course I don't buy every show, only the ones I like and/or can afford.
