This is what another smart guy found out:
It seems that WD took the site wdtvlive.com/wsapps/appservice.svc/json/browseapp offline. THIS IS CAUSING ALL THE (FREEZING) PROBLEMS OF FIRMWARES IN AT LEAST THE 2+ RANGE!
Redirect in your router www.wdtvlive.com to 127.0.0.1 or block the access to the WDTV for this site and all should work properly again.
More specifick: block if possible http://www.wdtvlive.com/wsapps/appservice.svc/json/browseapp but that will be hard to do on most routers.
This solution is for experts with the right router only. Lots of people don’t have the knowledge to program their router…
SHAME ON WD, YOU CAUSED THIS PROBLEM BY TAKING THIS SITE OFF LINE! THIS IS CAUSING ALL OUR PROBLEMS WORLD-WIDE! PLEASE PUT THIS SITE BACK ON LINE AND GIVE US OUR BOXES BACK! NOW YOU HAVE THE SOLUTION, THIS CAN’T BE SO HARD OR BE IGNORED ANYMORE!!
