Well, I finally got the iPlayer app loaded. I did this by randomly stumbling across a more recent firmware that the WD TV did not detect. You need version 1.01.26. A week later WD got back to me:
"Thank you for contacting Western Digital Customer Service and Support. [deleted].
Our apologies for the late response.
I am sorry to read that you have an issue with the media player. Our apologies for the inconvenience that this may have caused you.
I recommend to install the latest firmware update.
This firmware support as well the BBC iPlayer."
The link doesn’t work where I am but maybe it will for someone else.
I can’t say I’m very impressed with this thing so far. The iPlayer app actually works very well, but using Tunein and browsing for music on a local disc often make it freeze up, requiring a restart. Locating files elsewhere on my network is far too traumatic for the WD TV and I’ve given up in the hope that a future FW will fix things.
I also had to re-register for this forum in order to reply as my username was no longer recognized. Its not easy being a WD customer.
