I'm certainly having similar issues that include:
Choppy Playback. It was not uncommon to have choppy playback or the occasional pausing (streaming issue) before on large files 4gig+, now its happening with 800M files. What gives?
FileSharing - I have 3 WDTV's, one "master" where a 2T USB3.0 drive hosts all files. The other "slave" units connect via "WINDOWS SHARE". The dang thing never accepts the log on without me resetting the master unit. Then the slave medial players can see and connect. But then, after disconnecting and reconnecting 2 or 3 times, it loosed the login credentials and wont allow the slave units to connect without me resetting the master again.
Now I have three boxes that used to work PERFECTLY together. I bragged and got so many people to buy these things. I bought them for each of my inlaws and even one for my parents (7 units in all). Now the ones in my own home entertainment enviroment no longer work or function correctly.
Im dissapointed and really bummed.
