Hello, thank you for your feedback.
We noticed that some PGS subtitles extracted from 3D Blu-ray may be stretched or placed in wrong position. We will try to fix them in the future updates.
After testing 7.1 channel audio, we found that the SL(Surround Left) and SBL(Surround Back Left) have from/rear distinctions, though the positioning accuracy may not be very precise. We will take a further look into it.
