I was tired of pouring money into the computer. To add one piece of useful functionallity costed $80 on average. It was a good project to attempt and may be worth revisting when I’m willing to spend more money on a high-end system.
For now, I think it would be much easier and less expensive to simply purchase a standalone DVR such as a TiVo or ReplayTV box.
I sold the computer to a friend, so now I’m relying on my G4 for my personal needs, which continues to serve me well.
