Aside from capturing video on your computer, There currently is not any way to capture the data from the 622. Not sure if its encoded or not, or if someone has just not figured it out yet... However on other forums such as on Yahoo there is information on other dish dvr's for capturing the raw unencrypted data off the hard disc... I also seem to remember seeing a usb type device for a different reciever as well....
As a pro video editor myself, remember the fair use laws and dont use copyrighted materials for any other use... especially sporting events, that will get you burned big time...
And dont try and hack anything either, that is illegal as well.... And I hope those that do get burned as well....
Personally, I use the 510 dvr and make dvd copies of movies and shows for my own library to watch later....
