WD TV Live + WD Livewire - Video stuttering


I am using WD TV Live and WD livewire. I am able to see the folders of my shared folders having videos. But when i attempt to play them it takes quite some time to start and once it starts its only stuttering , I am not getting audio too. The player plays all videos well when connected to USB drive.

The shared folders contaning videos are on my HDD in my PC and some folders on ext drive connected to my PC on e-sata.  I am putting a screen shot of the WD Live wire Utility if that is of any help

I can play musuc files very well from my pc using the WD livewire. ANY kind of video, MPG, avi, mkv, simply stutters.

I connected the WD TV Live direct lan wire from router - all files play well.

Please post the full text output of mediainfo for one of the problem files.
