You are not alone. I have experienced the same problem as reported **Here **in this thread.
As you have explained, The problem is not seen with “Windows explorer” or WD TV Live series media players to some extent as long as you are at 1.04xx or 1.05.12 above but any other OS (I have tried Android Honeycomb OS as a test) and it fails to play any media type other than photos (JPG) as if someone decided at WD that - “what the heck” who would do that in Android OS? Just disable that option - Great! WD - You are wrong! - Please remember that the market to run on Android and IOS devices are in the millions of tablets and hand held devices - Guess what people do with those WiFi devices out there? - They connect to the router (or NAS share on the router) and try to gain access to the media as most of these devices have limited on device memory. and I am not alone.
To the community please make a note: It is a " FIRMWARE" bug. I made WD customer support aware of this problem in the early weeks of OCT of 2012 and I was hoping to see a fix but so far no luck. I had provided screenshots, Logs, directory listings, explaining the issues in great detail as seen with Android, IOS and other media devices that attempt to gain access to the NAS shares that My Net N900 xx series provides. Only partial fixes were seen to get implemented in 1.05.12 for the storage router. So far only Windows PCs and WD TV live streaming media boxes has access to Videos and Mp3 files.
IMHO, WD is new to Networking and It is sad to see that while their hardware is excellent (Much better than most other company’s product) it is the software / firmware which is cause for all probems. It is more of their QA department that is lacking experience. Someone in their QA department needs to get their acts together if they were to save their own product launch and their job and provide feedback to their developers who could code fixes for this problem. WD needs to have a broader test suites to validate a new firmware release out to the public as it is not only “Windows” that the end user uses these days. Wake up!
Please open a service ticket and submit your problems here: E-mail Support or Phone Support
This is a community forum and none of the community members here can help you with this particular problem If we all take time to open a service ticket by email (IMHO Easier than posting on community forums and ranting about it) explaining this problem in detail I am postive that WD developers will get the attention and release the fix.
Having said, WD does read these posts you make here, but it takes a long time for them to get their attention, Please contact WD directly rather than posting in the community.
