AudioSync plugin doesn't work correctly with mkv, mp4 or avi files. When you adjust, picture freezes and sound is still playing, movie also jumps to random places. This does not happen with all files. But all files also jump forward or reverse when you adjust and the actual adjustment doesn't seem to do nothing. Is this Vix image problem or once again one of those "great" VUPlus features? And again, my Dreambox 8000 (with original DM-image) handles those same files perfectly, movie continues to play and audio delay adjusts.
