I have a very general idea of what you're asking. I have a Digital Video Recorder with my satellite television device and I would like to burn disks of those recorded programs, but haven't tried because I don't know the steps. However:

My daughter has a video/receiver card given her by her father that apparently is used for transferring television and radio into the computer for processing. It is installed with software that assists with this. It was in the computer she shared with her brother, but I recently had to change out that computer's hard drive so I took out her card at the same time. She didn't use it much, but still plans to. I'll be installing it into her new (college-bound) computer before she leaves. With this card she can do all of what you're asking.

I have a software program that copies DVDs and it breaks them down into manageable file sizes, but as far as I know there is no editing feature involved. I think if you looked into the commercial DVD burning programs you'd find small programs buried in the system that let you do the editing, etc. I use Nero and it has lots of little programs like that for editing sound, and probably has something for editing video also.
