Sadly it's still skipping on HD badly...have to use the dolby prologic 2 track and get the amp to create 5.1, which leads to soft sound so not great! Sd seems to fair better but I have noticed the odd skip.
Like everyone else has said, all other apps don't suffer with this audio issue when the sound is passed via the TV to the amp on optical!
I have tried a hard reset and fresh install and the issue is still there, I have brought new cables and still skipping.
Music, stereo and prologic tracks are fine, but a 5.1...plex says no!
...deafening silence from plex on the bug...
