Well I don't have a problem with shows running into each other. I have both a digital & analog capture card for those rare instances. My main issue is that I'm not always around when the machine begins recording, so I won't always be able to tell when the cable box is powered on (if someone just left it on). So if there is any way to query through the firewire connection it's power state, that would save me a lot of trouble.
If not, would it be possible to use the s-video port of my pvr-150 to check if the box is sending a video stream, and therefore determine if the power is on?
