I posted a request to examine this issue here, but after two months and no updates, I'm getting very skeptical about WD actually addressing the issue.
My original post goes into some detail, but to make a long story short my WD TV Live SMP gen 3 completely screws up video output format detection in every single case save one. To the point where it actually DOWNSCALES 1080p HDX videos from Vudu to 720p before sending it to my 1080p display.
Nice. Really nice.
Has anyone else had this issue? Any tips on resolving it? Is it perhaps something confined to my particular hardware setup? I'm getting really tired of having to manually set the output format for each different video I watch.
