Just an update for everyone. Roku replaced my unit and I updated to  8.0.1 build 4090 when I booted up. DTS works fine now with no lag or sync issues. I'm streaming my HD content from my DS416 Synology NAS using Emby. Currently disconneted my Android TV as that struggles with Sync issues using t...

I've bought a Mi Box running android TV to see if that is any better with DTS.

Ihini everyone should contact Roku technical and complain. I did and they want me to replace the unit by sending it back. I will do this when I go on holiday as I have no content to watch while this happens.

I've had to do the same with DTS > DD. It is a real shame because the Roku specifications of being able to handle DTS was the selling point over every other streaming device. I feel a little cheated everything I play a DTS file. Not sure whether to give the android TV box a go or get an apple TV for...

Received a Roku for Christmas for my Plex and Emby server and I'm a little disappointed that any MKV video with DTS is painful to watch. End up using a DLNA through a 5 year old plasma TV to play back the passthrough DTS audio to my Denon amp. It managed DD and DD+ okay but struggles on the DTS chan...
