The different number of discs is up to you. The manufacturers can’t fit a whole season on one disc, so they break the seasons up into 4 or 5 disks Each. They have the same amount of content, but there are just different amount of episodes on each disk.

Typically, it’s cheaper to buy the whole series than individual seasons.
