I posted my issue here Constant Direct Play buffering
I just tested 75 Mbps content which only has two DTS:X audio streams and there wasn’t any stutter, lag or hangs. I also played plenty of “standard HD stuff” (1080p video with two 224 kbps AC3 stereo streams) in the last three days and didn’t had any problems too.
Really looks like as soon as a TrueHD audio stream is in the file, Plex can’t handle it.
I thought it was my WiFi or PMS and went crazy finding the issue but looks like Plex f*** up again 
Why releasing a beta when nobody listens to the feedback. Btw. I’m NOT in the beta channel for a very good reason.
@drzoidberg33 help us please!
This issue also affects Android TVs, not just nVIDIA Shield TV.
