Just want to say with the last update(s) you nailed it! The smearing is gone!
For me now only these issues are still open:
and occasionally, despite buffering being all ok, the sound continues but the video is in slomo. Then after a few seconds (can be like 10 seconds) it suddenly syncs again and runs fine.
In a important scene it’s not appreciated.
Something new since last update(s) is that occasionally there is suddenly a frame popup. Like in the movie Fight Club where Tyler added a single frame to the movie. That’s what I sometimes see. Like 1 in 3 movies/episodes it happens 1 time.
