How to delete your podcast in IPAD

As we can download many free podcasts in PAD, but somehow the user interface of ipod(in ipad) isn't smart. You should get into the item which you wanna delete, then swiping your finger go through the item. Obviously, a Delete mark will be showing up and tap it. 'Cos it doesn't like you tap the item 2~3 seconds them a "X" or delete mark will appear. So...remember swipe your finger!!!
