When you want to add part of a TV series to your list (for example, Season 1 of SomeSuchSeries), does Netflix send you the complete Season 1? Or does it split up the discs, as they would appear if you bought them in a store (as in episodes 1-4 on one disc, episodes 5-8 on another, etc.) and then send you one disc at a time as it becomes available?

My library has the series I want to catch up on (I started watching beginning Season 4--in repeats--so I have 3 seasons to watch), but it splits them up to individual discs, so it takes forever to get them in the right order (it's useless, say, to try to reserve the entire series because you don't know if Season 2, episodes 5-8 will become available before the disc that has episodes 1-4, and it's hard to "game" the system to time it to your benefit).
