The issue arose with 1.03.49 (the firmware update that implemented DVD Menu Functionality). Since that update, the WDTV Live downmixes 5.1 from DVD .iso’s poorly. This is a fundamental function of a media player and should’ve been addressed immediately, but seems to have persisted through all firmware updates since that one.
Extensive testing has been done by numerous users - for more info, see:

The problem is only with the 5.1 downmix to stereo from DVD .iso’s. 5.1 tracks from all other containers seem to downmix perfectly. This is not an issue with our ripping software - so don’t suggest it. This is not an issue with our receivers - so don’t suggest it. I run analog stereo out from the box to stereo connections on the receiver. The .iso’s play perfectly on a PC, but not from the WDTV Live. The 2.0 tracks on DVD rips are perfectly normal (like the audio in the menus), but the 5.1 tracks are extremely quiet. So if you are using the WDTV Live to watch a DVD .iso, you have to adjust the volume WAY up after you leave the menu and begin watching the feature/episodes…then remember to turn it back down before the menu comes up again or you’ll nearly blow you’re speakers and scare the ■■■■ out of your neighbors…
WD, please address this issue. I’ve waited patiently for a long time now hoping to see this get fixed. I was extremely pleased with the WDTV Live when I first got it and have suggested it to many people that I know, but I have since become cautious when it comes to bragging about its merits. As I stated before, this is a fundamental problem with the box and will eventually lead me to another company’s product if it’s not rectified.
Thanks.
