I’ve seen many posts on this subject already…there’s not one clear answer (from WD). I’ve asked Twonky support why MKV files won’t play; here’s their answer:
"It seems to be an issue with the old version of Twonky Server installed on your NAS drive.
We would recommend you to upgrade to the latest version of Twonky Server.
Since this is an OEM version, you need to contact the device manufacturer for a firmware update with the latest version of Twonky Server.
You can also manually Upgrade to Twonky Server v 7.0.5 from the following link:
If you upgrade manually then you will need to purchase a license key for it.
License key can be purchased from the following link:
Once you update the software, share the content and let us know if the issue still persists."
Now why is a NAS that I have recently bought, equipped with an extremely old version of the DLNA Twonky server software? I also don’t ‘get’ why, when I can manually install the working version, I have to buy a license for that…will WD refund my extra expenses? I think not! I think WD isn’t advertising the NAS correctly streaming all kinds of media with almost zero effort.
Also…pictures via the iPhone app ‘WD Photos’ are extremely slowly inventarised on the NAS or in the app itself.
If I knew this before…I probably wouldn’t have bought it.
