DON'T PANIC!! all is not lost... basically any content downloaded from itunes is free for life to re-download, they do that for exactly that point hehe, simply re-download the film on ur ipod or computer. If you download content on your iPhone or iTouch and go to sync it with your computer it will remove content from the device. To solve this issue, When you have downloaded content on your device, Make sure the "auto sync" option is turned off on the computer, Right click the device on the left side of itunes and select "transfer purchaces" This will move any new purchaced data to the computer and will keep it safe :D i hope this makes sense. If you need any more help just send me a PM.
