I have a number of 4gb BDrips in .m2ts format which I stream via AFP from a NAS on my local network. Although they play correctly, if I try to fast forward/rewind or turn subtitles on, the aTV will freeze and need to be reset (holding menu/down for 7 secs). Smaller files (2-3gb) in .mp4 format do not experience this problem.
Does anyone else have this problem or is it a known issue? Any fix known?
