OK... I'm not really used to getting shows off itunes for my ipod and not too long ago I bought some Kyle XY and Secret Life episodes to put on the ipod and last time I hooked my ipod up to sync, I noticed the episodes I watched were deleted off there....

is that supposed to happen? do I have to pay to get the episodes back or does redownloading them mean paying for them again?

thanks for any and all help with this!
