I just updated to firmware ver. 1.05.04 so I can use a 2.5TB drive in addition to the 2TB drive I was already using without issue. Both drives are USB directly into the player.
After the update, everything appears to work fine with the exception of a stutter of 1 - 2 sec every 30 -45 seconds on 720P MKV files. File sizes are between 4 - 6 GB.
These files played without issue before the firmware update and are playing off the same drive as before. The only difference is that the firmware update was applied. I have not tested how the same file plays off the new drive, that is next on my list.
Anyone else experiencing this issue? I am reluctant to downgrade the firmware since I wouldn’t be able to use the bigger hard drive.
