Hello, I have the WD TV Live + as well. I noticed that while wathcing a movie as well my sound would go silent for .5 of a second then resume. I have my WDTVLive+ hooked up to my TV via HDMI and to my reciver via Optical.
When I have the audio set to DIGITAL I got this stutter problem.
Can WD clarify that when the unit is set to DIGTIAL does it send the sound/audio out over both the HDMI and the optical out.
What you can do is dl a few of these 5.1 test files and play them. My receiver when it detects differnt digital signals its displays which format it’s receiving: Denon AVR3801
When playing other HD movies I do see it detect it as either DTS, or Digital Dolby and works fine so I know the signal out is working right, just this stutter is bothering me.
