So basically, I've been looking into building a DVR system first and foremost, and have thought about also making it a media center/home theater system as well.

I wanted to know if any of you have built DVR systems before or know people who have and whatever information you could give. I've found a few good resources, like byodvr.com

I'm open to everything...whether it be XP with SageTV, Linux with MythTV, etc.

Thanks...
