Okay I know I must be lame. Before the Hopper and on every other DVR I have had. There is a place to as example pull up DVR folder for Seinfeld and simply place a check in box next to all episodes I want to delete and then simply choose delete. Verify and then its gone.
On the Hopper I only find I can delete one episode at a time and its slow and a pain. I can not find any other way?
