I watch it live on Sunday nights (eastern time) and then I rewatch it again on the DVR. Throughout the week, there’s a good chance I’ll watch the episode again on Hulu or on Demand or DVR. Whichever suits me at the time. (Sometimes evil weather alerts marred my DVRed broadcast in which case I want to be able to see it without those.) I plan to buy the DVDs (or probably the Blu-ray) too.
