I bought two episodes on itunes and when I try to put them on my itouch it wont let me. I tried the whole summary thing and it wont let me. It starts sync and then it says, "Was not copied to the ipod because it cannot be played on this ipod". and for the other episode it says, "It was not copied to the ipod because you are not authorized for it on this computer." PLEASE HELP. I bought the episodes and want to see them badly
