How can I transfer recorded programs from my digital TV terminal to my computer?

I'm going to be getting a new digital TV terminal that has 80GB hard drive to store recorded programs. Is there a way I can transfer this to my computer so as not to keep deleting programs for saving space?
What's the make and model number of the terminal? Some do have the transfer capability built into the unit (you'll have to have a USB cord connected from the unit to your computer), but I can't tell you for sure without more information.
If you record content to a blank DVD-R you can take that DVD and rip it with some software. You'll need a DVD drive in your system.

I can link you to a good freeware DVD ripping software if you'd like.
