I'm not sure if this is the right place to post this topic, but I purchased a WDTV Live the weekend as a DNLA renderer. I set it up and it worked perfectly playing all types of music (mp3 and mainly wma lossless) and video (HD mkv's and ifo's) using the 'Generic DLNA' server configuration.
I used webremote to control what was playing on either the server in the lounge of the WDTV in the kitchen and it worked like a dream effortlessly switching between the 2 xones playing HD movies on both simultaneously
However the next day I couldn't get it to work at all. Neither music or video would work, and in MC the WDTV was just constantly 'waiting' and nothing would play at all.
After hours of messing around, I deduced that it seems that an update to the latest WDTV firmware caused the unit to crash whenever MC streamed 'converted' audio or video to the unit.
My music collection is all WMA lossless, so MC must assume that the WDTV cannot play it so converts to mp3 then streams, thus crashing .
It's the same for my mkv's.
The workaround is for music, set the 'Generic DLNA' settings to 'always convert' and select 'uncompressed' as the audio format.
For video, change the setting to 'never convert'.
Hopefully someone will find this useful
