The past seasons would be an On Demand feature. We have DirecTV and the On Demand modem was free and very easy to hook up. I'm not sure if that was a special they were running at the time or not, but they called up one day out of the blue and said "why don't you have On Demand..it's free and easy....?" And for a change it was...LOL. It's great. The only drawback would be if your wireless signal is slow at your house. Ours lags at times, especially when my son is destroying the universe on his Xbox, but other than that no problemo.
Because I work from home 2 days/week, I have business class high speed internet so that wouldn't be an issue. I'm more concerned about what kind of hoops I'll need to jump through or if DirecTV will try to extend my contract because I'm making a change. The On Demand might require a longer commitment than I want to make, too. Might be I'd be better off buying the DVDs!
