Hi, for me zero cache causes play back issues, so I just have it set to no advanced setting and clear cache often. Here a page from kodi site explaining zero cache.
1.1 "Zero" cache
A lot of people see references to a "zero cache". This is a specific setting for the video cache to use local storage (such as a hard drive) instead of RAM. This setting is not needed for most users, even if you only have 1GB of RAM total.
Note: The zero cache mode/settings does not improve video buffering or performance.
Users should not use the zero cache mode/settings on a device that does not have a lot of free internal space, such as an Amazon Fire TV, OUYA, or other devices with only about 8GB of local space total. Such devices will only have about 4GB of available space when you deduct the OS and other files that are used, and this is rarely enough space for a full length movie. If Kodi attempts to use the local drive without having enough space then video will either suddenly stop, or Kodi could even crash.
Like all video cache settings and modes, the user does not need to manually "empty" the cache when using the "zero" setting. Kodi will automatically empty such temporary files.
