Unfortunately, violent jerks and strong sound skips BluRayISOS. NAS or network as errors can I exclude, as same films and the same configuration tested with other players. Otherwise this would be a really great player that plays everything and AVCHD files in the same folder plays consecutively without always the next file reselected (restart) must be. Also keep this player counterclockwise O! Play Mini Plus and the O! Play HD2 sorting as dictated by the NAS in and not throw everything in a folder at once. Presumably the network interface this player is not fast enough or the processor too slow ?? A real shame.
