DTS Audio 100% CPU load since 1.4 or 1.5

Some days ago I got Problems with some videos. Today I now can break it down to videos with DTS Audio. I think this behaviour exists since 1.4.

Server Version: 1.5.0.3501 on Synology NAS (DS1815+)
App Version: latest ATV 4 Version

Not sure at the moment if this Problem exists only with ATV or with every Player but I saw a different posting correlate with other client.

So anyone else with Problems here? What do you need to help me here?
