Hi all, I recently bought a Vizio Co-star and WD MyBookLive a private cloud. I've already connected and I can see pictures and listen to music using the Twonky on the wd and vimu on vizio. The problem arises with the videos, i could play some videos but without sound ... and I cant play MKV because when i try there is an audio format error report. Using DicePlayer on my tablet i can see all the videos on the tablet WITHOUT ANY problem, which leads me to suspect it's a problem of Vizio codecs. Since both devices I have the latest firmware installed. Can someone help me with this? Thank you!
