I have this ongoing problem for some time now - and it seems to get worse everyday. I have a WDTV Live box connected to my PC (Windows 7) via ethernet. The box is connected to the TV via HDMI. There's no problem with the video - it's the audio that's the trouble. I've connected the box to my Panasonic SA-HT900 (Home Theatre) via an optical cable. It won't play the audio on DTS encoded videos (don't really know why), but what really bugs me is when I play DD5.1. It takes longer and longer to get the Panasonic to output the audio without stuttering (and the display flashing) all the time. Today for instance I've rebooted the PC twice and the WDTV box and after an hour I'm no closer to watching a DD5.1 encoded film. Other times - very rare I might add - it plays flawlessly as soon as I switch it on. I've tried checking and re-checking the network connection; changing the digital/optical properties etc. I've even used Twonky and PS3 Media Server which work sporadically along with ordinary Windows network connections. NOTHING seems to solve the problem once and for all. Any ideas would be greatly welcome as I'm reaching the point of swapping out the box for another brand.
