I bought a WDTV Live a few months ago. And I’m happy with it.
Till now I always connected my USB HDD WD Elements 1TB to my WDTV without major problems.
I bought a few days a Cable Router (Hitron BVW 3653) with a USB port that can turn a USB Disk into a NAS. I connected the WDTV with an Ethernet cable to this router.
The problem is:
If the USB disk is connected directly to WDTV Live the subtitles are played correctly, but if I connect this USB disk to the router, turning the router into a NAS and the WDTV to the router, I can see the video perfectly without flaws but when I try to select the subtitles I receive the information that there are no Subs in the folder.
