Not So Watch Instantly

Stargate SG-1 season 3 on Netflix watch instantly requires getting the disks for episodes 5, 15, & 20. Why? My best guess is unlicensed for the medium because of an actor.

Netflix needs to work on providing a warning when episodes of a television show require getting the dvd so I can plan ahead. Also only the select another episode shows the dvd only icon. The main screen with play just skipped 5.

Very poor user experience design here.
