I've come across a few ipad podcast behaviours that do not occur on the iphone 3GS
1. I synced the last three episodes of a number of podcasts,I then downloaded a new episode via the ipad.After downloading I noticed in the podcast list that some podcasts had two entries (see screen shot,Engadget gdgt weekly)
If you look under each of the duplicated entries they contain the same episodes
2. Podcasts with chapters.If you have several episodes of the same podcast and select a chapter from say the second or third episode the corresponding chapter of the first episode plays
3. Podcasts with pictures that change with each chapter do not work on the ipad but do on the iphone 3GS
