My plan is also to use hard drive for storage. However for important documents, family photos, video clips, and when space allows, movies, I would like an extra way to archive.
But when my family wants to view different clips, the intention is still to navigate the hard drive, find the clip and play!
My TV can directly access a USB flash drive (fat32), navigate its folder structure and fetch h.264 movies.
So for H.265 on BD data discs, I would play through the computer instead, with the computer connected to the TV, right?
