In preparation for my xmas iPod touch, i subscribed to a few video podcast (some CNBC money reports and Mac tips) and i have a few questions. 1. I have iTunes set to check for new podcasts every hour. Does this mean if a new podcast is available it will be downloaded immediately? 2. In podcast settings, i chose to keep the last 2 episodes. When a newer one is downloaded, will the now 3rd newest be deleted from my Mac? 3. How does the formatting of the video work with the touch? Syncing it as is will be fine or does it have to be converted? Thanks in advance.
