My TV doesn’t have a data drive, I’m not sure about whether it can access ANY network–but it’s not MY TV that I’m all that concerned about, it’s what the players will use at home, so maybe I’ll just have to be content with a few seconds playing slowly.
It’s just at the very beginning that it lags, after that, it will play at regular speed for the entire game. There has just been one file where the lag lasted about 10 seconds that really bothered me.
I do have an external SanDisk Extreme SSD drive, but it still has to connect to the TV via USB 3, and the lag time is exactly the same with the SSD as with the 3.0 jump drives.
These are given to the players in the anticipation that they will watch these for years to come, so maybe by that time, they will have devices that can play it flawlessly.
Thanks to all who took the time to help out.
