My issue with this newly removed feature is different although the cause is still the sudden removal of this feature which had worked fine for 18 months.
I run my hdmi to my TV and my optical to my receiver.
This allowed me to:
1) play through the TV speakers when watching normal programming
2) play through my receiver for action or other sound dependent films or for music.
This worked fine for a year and a half and suddenly I can no longer use either. I have to pick sound though optical or sound through hdmi when both worked for every single firmware until the most recent.
I called WD and got a SEVERE run around with three techs telling me there was no change in this. Finally a supervisor confirmed you CANNOT use both. Bad enough that we have not been able to use analog output simultaneity, but you could always use the two digital outputs (hdmi and optical simultaneously, and now you cannot.
I asked if it would be fixed and they said: no. **bleep**!
