You are transcoding, and not very quickly. When you skip ahead it has to build up a buffer since it is not really "getting ahead". When you skip back to where you've already watched, its because the transcode from that point is still on the disk.

The N3450 just isn't a super fast transcoder, especially when you are burning in the subtitles. Without subtitles it would probably transcode quite a bit faster, but subtitle burn-in involves the CPU and not just the GPU.

The reason only the Firestick is transcoding is due to exoplayer not fully supporting ASS subtitles. It supports basic, un-styled, ASS subtitles. Most browsers fully support ASS subs, as does Kodi.
