can anybody help me with opening and playing the movies in itunes

A little off-topic here. But to import & play videos in iTunes they need to be mpeg 4 or H.264 which is simply a further developed version of mpeg 4. To play videos, double-click video file or else, select & press play. You will find videos in main library, or if you have iTunes 7 you will find them in the video list just below the music library list. So be sure you add mpeg 4 videos to iTunes, not any other type (not mpeg 1 or 2 either.) (Further off topic, I've found H.264 to be a very effective format to convert videos to. Even much more effective than divx in regards to size & quality. No wonder they were considering using this format for the new high definition dvd's instead of mpeg2 that's used on dvd's now.)
