I basically use my HTPC as a DVD/music server. It's only on when I'm using it but now I'd like to try it as a DVR. How do you guys setup your systems to be able to pop on when the PC is set to record a TV show then go back off or to sleep when done? Is it a sleep mode setting of some kind? I'm in the dark on this one. I'd leave it on all the time but I have a slight heat issue which I plan to address soon. It would be nice for the PC to be in a sleep mode at all times. My system is currently using Windows XP Pro, and MyHTPC. I might move to Win XP Media Center Edition 2005 to cover the DVR function. As for video cards I currently have an ATI AIW 9700 Pro, and a yet to be installed ATI HDTV Wonder card. Thanks in advance for any help.
