I haven’t played anything but video with wiimc but the files I am playing are mpeg’s in dvd format 2,700kps 720×480 29.97fps…. I hate searching for the dvds so i just put them on my pc for my xbox and wii to watch them with out having to get up and the kids don’t destroy the disc … but this problem is interment it doesn’t happen every movie or all the time …
but to answer your question the wiimote syncs right back as soon as i hit a button… I also tried to update the ios’s on my console as they were very out of date and the problem is not as bad now but it will still do it.
