My wife subscribes to Netflix, at the cheapest "plan" they have.
What we did was to hook my computer (dual monitor outputs) to the 56' big screen in our media room, and the audio also (the TV has front panel hookups for audio and vid)
Because her Netflix account has "watch it now" we just load up what we want to watch and away we go!
In the past week I started watching Lost and we've gotton to episode 12 of season 2 (damn thing is addicting)
We don't subscribe to any Sat or Cable anymore.
Oh, DTV................................SUCKS.
