Regarding Hulu's subscription-based offering Hulu Plus possibly offering a short-term promotional price of $4.99/month

Fox, is looking to protect DVD sales and exact top dollar for the programs in syndication, according to a person with knowledge of the situation. Exposure on Hulu, Fox fears, would devalue the worth of the shows.
So I guess even if a new Trek series weren't on a linear TV channel CBS Home Video would feel the same way?
