What is Playback‐DNI

[jwilson]

I noticed my tablet was running slower. Usally that means internal memory is running low. So I checked, and the djigo5 directory was taking up over 4 gig. So I searched the directories to see where the space was. Video cache was 2 gig, so I deleted that. Then, the only other big directory was Playback‐DNI. So I moved it to my SD card. Does anyone know what it is? Thanks
