everything was working last night but this morning everytime i try to play a movie from my ipod or a youtube clip it says "This movie could not be played" when i try to play songs it looks like its playing but the song doesnt start. the progress bar shows the song at the beginning. Ive turned the volume up and down and it makes no diffrence. Then I tried to pause and restart the song but nothing happens when i click the play button, just sits there. is my ipod screwed? am I going to have to restore it again?
