Ok, when I recorded something which lasts several hours (the video play time being several hours), it no longer plays in mplayerc, it gives a cannot render the file message at bottom of player, before it played fine. All play lengths are fine up to like 1 hour and a half, but then when i play something a few hours long i get the message, the video works fine in other players. mplayerc is my main player and the one i use for everything and so highly do not want to start using another player.
