fyi, am using latest, v1.01.24 firmware.
can someone test this out to see if they get the same results?
share a Folder with 2 files in it Only ie. the video file and the thumbnail:
eg. Gladiator containing Gladiator.mkv and Gladiator.jpg (i also tested with .mp4 and .jpg with same results)
In WDTV, go to Video-YourPC-Network Shares-Gladiator
and Press PLAY on your Remote with the Gladiator folder selected.
Do you get a reboot?
