Okay, here's what I did
I right click on the podcast, go to Get Info, and down to start time. I click .50 which means that it cuts off the first 50 seconds of the podcast, right? Then I click play. At that point, in iTunes, it will play from that starting point. But if I choosed to replay it, it continues to go back to the beginning and then also when I sync it to my iPod, the first 50 seconds are still there.
I don't know anything about iMovie either...so I feel lost.
