Some new things.
1. Subtitles sync properly when fast forwarding m2ts files. Previously could be several minutes out of sync.
2. When scrolling through pages of Video jpgs works fine but going back up the page sometimes groups of jpgs don't display but scrolling back down again there they are again.
3: rewind is still iffy. Go back a couple of minutes press play and you are still where you are when you started the rewind.
Overall it's great. screens look so cool with jpgs and more mkvs now have working audio.
Personally don't find the pause before video files load a problem.
