* Licensing restrictions: Netflix doesn't always have the rights to stream all episodes of a show, especially older ones. The rights might be held by a different company, or the studio might choose to only license certain episodes for streaming.
* Availability in your region: Some shows are only available for streaming in certain regions. If you're in a region where the streaming rights are limited, you might see "disc only" for certain episodes.
* Technical issues: Occasionally, there might be technical issues with streaming certain episodes. This could be due to a problem with the source files, or it could be a temporary issue on Netflix's end.
* Show availability: It's possible that the show is no longer available for streaming on Netflix, even though the DVDs are still available.
To figure out why a particular episode says "disc only," you can:
* Check the Netflix help page: Search for information on the specific show you're looking for. You may find information about licensing restrictions or availability in your region.
* Contact Netflix support: You can contact Netflix customer service for more information about why a specific episode is unavailable for streaming.
While it can be frustrating to see "disc only" on some episodes, remember that it's often due to licensing and availability restrictions. If you really want to watch the missing episodes, you may need to purchase a DVD.
